Answer 21

is a measure of a chemical substance’s (solute’s) ability to dissolve in a given solvent

Question 22

Oxidation-reduction reactions

Answer 22

involve the transfer of electrons from one reactant to the other

Question 23

easy way to remember oxidation and reduction

Answer 23

OILRIG, Oxidation is loss(of electrons), Reduction is gain(of electrons)

Question 24

oxidation number

Answer 24

Oxidation state, represents the degree of oxidation of a chemical species. The oxidation number for a pure element is zero

Question 25

Four rules for assigning oxidation numbers to chemical species

Answer 25

1. Oxidation state of any atom in its elemental state is zero 2. oxidation state of a monoatomic ion is equal to its charge 3. Sum of the oxidation numbers in a neutral compound is zero 4. sum of the oxidation numbers in a polyatomic ion is equal to the charge of the polyatomic ion
