Question

A solution (5 mL) of an acid X is completely neutralized by y mL of 1 M NaOH. The same volume (y mL) of 1 M NaOH is required to neutralize 10 mL of 0.6 M of $H_{2}S{O}_4$ completely. The normality (N) of the acid X is

• A. 1.2
• B. 2.4
• C. 4.8
• D. 0.6

Answer 1

The correct option is B 2.4

$NaOH$ (Number of equivalent = $H_{2}S{O}_4$ (Number of equivalent)
$(1\times 1)\times y=(0.6\times 2)\times 10y=12mL$
Now,
Acid (Number of equivalent) = $NaOH$(Number of equivalent)
N × 5 = (1 × 1) × 12
= 2.4 N
