H2SO4 + 2NaOH → Na2SO4 + 2H2O Answer:
In this reaction, 2 moles of H+ ions (2 equivalents)from sulfuric acid (H2SO4) react with NaOH to form sodium sulfate and water.
Normality(N) = 2.0
2. What is the normality of 1.0 M H3PO4 in the following reaction?
H3AsO4 + 2NaOH → Na2HAsO4 + 2H2O Answer:
In this reaction, only 2 of the three available H+ ions (2 equivalents) from arsenic acid (H3AsO4) react with NaOH to form Na2HAsO4 and water.
Normality(N) = 2.0

What Is Normality Of A Solution?
Definition :-
Normality refers to number of gram equivalent of substance dissolved in per liter of it's solution.
Here number of gram equivalent is obtained by dividing weight of substance in gram by the equivalent weight of substance.
Formula :-
Normality is a rarely used expression which indicates the concentration of a solution. It is defined as the gram equivalent weight per liter of solution.
Examples:-
1. What is the normality of 1.0 M H2SO4 in the following reaction?In this reaction, 2 moles of H+ ions (2 equivalents)from sulfuric acid (H2SO4) react with NaOH to form sodium sulfate and water.
Normality(N) = Molarity(M) x number of equivalents
Normality(N) = 1.0 x 2Normality(N) = 2.0
2. What is the normality of 1.0 M H3PO4 in the following reaction?
In this reaction, only 2 of the three available H+ ions (2 equivalents) from arsenic acid (H3AsO4) react with NaOH to form Na2HAsO4 and water.
Normality(N) = Molarity(M) x number of equivalents
Normality(N) = 1.0 x 2Normality(N) = 2.0
