Section 15.4- Equivalents and Normality

Question 1

Instead of using ke amounts of acids and bases in neutralization reactions, it is more convenient to use amounts that are

Answer 1

Chemically equivalent

Question 2

The amount (number of moles) of an acid that will supply 1 mol of protons or the amount of base that will supply 1 mol of hydroxide ions

Answer 2

One equivalent

Question 3

The mass per equivalence of that acid or base

Answer 3

Equivalent mass

Question 4

Equating for equivalent mass

Answer 4

Eq mass = molar mass of acid or base
————————————
Number of ionizable H atoms
Or OH ions per formula unit

Question 5

The advantage of using equivalents is that

Answer 5

One equivalent of any acid reacts with one equivalent of any base

Question 6

The number of moles per liter of solution

Answer 6

Molarity

Question 7

The concentration of a solution expressed as the number of equivalents per liter of solution.

Answer 7

Normality

Question 8

Equations for normality:

Answer 8

N = equivalents solute/ liters solution

N = molarity x # equivalents
