In a titration, what is the name of the substance that is being determined?

Answers

In a titration, the substance that is unknown and being identified is called analyte. A titration is where a known solution or concentration called the titrant is used to identify and measure an unknown substance which is the analyte.

Titration is done using a titrant and analyte. In a titration the name of the substance that is being determined is called the analyte.

What is titration?

Titration is an analytical method of finding concentration of a solution using a known concentration of a standard reagent. The standard reagent is called titrant and the solution with unknown concentration is called analyte.

There are different types of titrations such as acid-base titration, complexometric titration, potentiometric titrations etc. All these need an indicator and used to determine the end point by a color change.

In acid-base titration, acid is taken in the burette and base in the pipette and using an indicator the end point is noted.

In complexometric titration, metal solutions are analyzed with an indicator capable of forming complex with the metal. In this way in all types of titrations the normality or molarity of the solution.

Hence, the substance being determined using titration is called analyte.

Why doesn't potassium fluoride conduct electricity as a solid?

Answers

potassium flouride is an ionic compound and ionic compounds do not conduct electricity in solid form instead it conducts electricity in molten state.Ionic compounds do not conduct electricity in solid state because their ions are fixed while in molten form the ions are free

Final answer:

Potassium fluoride doesn't conduct electricity as a solid because its ions are locked in a fixed crystal lattice structure, and aren't free to move. However, when dissolved or melted, the ions can move freely, making it a conductor. Another factor is the large band gap in its molecular orbitals which prevents easy movement of electrons.

Explanation:

Potassium fluoride, like all ionic compounds, does not conduct electricity in its solid state because the ions in ionic solids are tightly held together by strong electrostatic attractions and thus, aren't free to move. The capacity to conduct electricity requires charged particles to move freely. In substances like potassium fluoride, these charges are locked in a fixed position within a crystal lattice structure.

However, this changes when potassium fluoride is either dissolved in water or melted, essentially when it is no longer in a solid state. In these cases, the ions of potassium and fluoride are free to move around and can carry an electric current. This freedom of movement of ions is referred as the substance being in a molten or dissolved state.

The concepts of valence and conduction bands in molecular orbitals of solids also play a role. In conductors, only a very small amount of energy is required to move electrons from the valence band to the conduction band whereas in insulators like potassium fluoride in its solid state, the band gap is large, making it a poor conductor of electricity.

Which is an example of a chemical change?
a.the separation of a mixture into its components
b.the separation of a compound into its elements
c.the separation of gases from liquids
d.the separation of air into oxygen, nitrogen, and other components?

Answers

the separation of air into oxygen, nitrogen, and other components?

Final answer:

A chemical change involves the conversion of substances into different substances, as in the separation of a compound into its elements which requires breaking chemical bonds, unlike a physical change.

Explanation:

An example of a chemical change is the separation of a compound into its elements. This process involves breaking chemical bonds and forming new substances with different properties than those of the original compound. For instance, table salt (a compound of sodium and chlorine) cannot be separated into sodium and chlorine by physical means like filtering or distillation; it requires a chemical process. In contrast, physical changes, such as the separation of a mixture or the condensation of steam, do not produce new substances and are reversible.

Burning of gasoline and the souring of milk are also examples of chemical changes, where original substances are transformed into new ones, such as carbon dioxide and water from gasoline, and denatured proteins and produced acid from milk.

A classic chemical change can be observed when natural gas is burned in a furnace, converting methane and oxygen into water and carbon dioxide, signifying not just a visual change but a molecular transformation as well.

Calcium chlorate has the formula Ca(ClO3)2. Which best describes the structure of calcium chlorate? One molecule of calcium chlorate contains nine atoms. Calcium chlorate is an element that contains three atoms. It takes nine different elements to make one molecule of calcium chlorate. Calcium chlorate contains two Ca groups.

Answers

The formula Ca(ClO3)2 breaks down to: 1 calcium atom, 2 chlorine atoms, and 6 oxygen atoms. Therefore:

One molecule of calcium chlorate contains 9 atoms [correct]

Calcium chlorate is not an element, nor does the molecule contain only 3 atoms [incorrect]

It does not take 9 different elements - just the three elements we listed [incorrect]

Calcium chloride only contains one Ca group [incorrect]

The formula Ca(ClO3)2 breaks down to 1 calcium atom, 2 chlorine atoms, and 6 oxygen atoms. One molecule of calcium chlorate contains 9 atoms. Thus the correct option is A.

How calcium chlorate is formed?

Calcium chlorate is formed by passing chlorine gas through a hot suspension of calcium hydroxide in water, producing calcium hypochlorite, which disproportionate when heated with excess chlorine to give calcium chlorate and calcium chloride.

6 Ca(OH)2 + 6 Cl2 → Ca(ClO3)2 + 5 CaCl2 + 6 H2O

This is also the first step of the Liebig process for the manufacture of potassium chlorate. Liebig's method is used for the estimation of carbon and hydrogen.

Carbon monoxide (co ) is used as a purifying gas in mond's process to produce nickel from its ores. what type of bonding occurs between the atoms of a co molecule?

Answers

Carbon monoxide has a special type of bond that is a triple bond. The triple bond consists of two covalent bonds in which the elements share some of the outer electrons and then is a dative covalent bond. This is a bond that gives the elements a special kind of group and power in relation to the strength when attempting to break it up.

Answer is: covalent bond.

Covalent bond is bond between nonmetals. Carbon (C) and oxygen (O) are nonmetals.

Carbon atom and oxygen atom are connected by a triple bond (six shared electrons in three bonding molecular orbitals) that is formed of two covalent bonds and one dative covalent bond.

Dative covalent bond is formed by two electrons derive from the oxygen atom.

Carbon monoxide is a colorless, odorless, toxic and tasteless gas.

Which is the best description of the chemical reaction shown here in aqueous solution? ch3ch2cooh (aq) ↔ ch3ch2coo- (aq) + h+ (aq)?

Answers

Final answer:

The chemical reaction is an equilibrium reaction representing the partial dissociation of a weak acid, acetic acid, into acetate ions and hydrogen ions in aqueous solution.

Explanation:

The chemical reaction CH3CH2COOH (aq) ↔ CH3CH2COO- (aq) + H+ (aq) in aqueous solution is best described as the dissociation of a weak acid in water. This reaction is written as an equilibrium because it does not go to completion, and both the forward (dissociation) and reverse (re-association) reactions are occurring simultaneously. This reaction shows acetic acid partially ionizing in water to form acetate ions (CH3CH2COO-) and hydrogen ions (H+). The double arrows indicate that the reaction can proceed in both the formation and the re-formation of acetic acid. This behavior is common among weak acids, which do not completely dissociate in water.

How many moles al2o3 are needed to neutralize 1 mole of hcl?

Answers

*Given
1 mole of HCl

*Solution

Chemical Reaction:

[tex] Al_{2}O_{3(s)} [/tex] + [tex] 6HCl_{(aq)} [/tex] -----> [tex] 2AlCl_{3(aq)} [/tex] + [tex] 3H_{2}O_{(l)} [/tex]

The chemical reaction is a double displacement reaction, where the oxide ions of the
[tex] Al_{2}O_{3} [/tex] were "transferred" to the hydrogen ions of HCl to form [tex] H_{2}O [/tex], while the chloride ions of HCl were "transferred" to the aluminum ions of [tex] Al_{2}O_{3} [/tex] to form [tex] AlCl_{3} [/tex].

Arising from the law of mass conservation where the mass of the reactants must equal the mass of the products, chemical equations must therefore be balanced. Another way of interpreting the law of conservation of mass is that the number of moles for every ELEMENT (not molecule or compound) in the reactants, must equal the number of moles of every ELEMENT in the products. This principle allows us to balance chemical reactions.

Looking at the chemical reaction above, we can see that the 2 moles of Al in the reactant is balanced by 2 moles of Al in the product; 3 moles of O in the reactant is balanced by 3 moles of O in the products; and finally, 6 moles of H, and 6 moles of Cl in the reactant, are also balanced by 6 moles of H, and 6 moles of Cl in the products, respectively.

For every mole of HCl,

[tex] 1mol HCl [/tex] X [tex] \frac{1 mol Al_{2}O_{3}}{6 mol HCl} [/tex] = 1/6

Thus, 1 mol of HCl would need 1/6 mol of [tex] Al_{2}O_{3} [/tex] to completely react and form products.
