Question

$2N$ $HCl$ solution will have same molar concentration as a:

• A. $4.0N{H}_2{SO}_4$
• B. $0.5N{H}_2{SO}_4$
• C. $1N{H}_2{SO}_4$
• D. $2N{H}_2{SO}_4$

Answer 1

The correct option is A $4.0N{H}_2{SO}_4$

Relationship between normality and molar concentration is
Normality = n x molarity (M)
Where, n=the number of moles of $H^{+}$ per mole of the compound that a solute is capable of releasing [acid] on reacting with base.
In case of $HCl$,
$n=1$
Hence, 2N$HCl$ solution $\approx 2MHCl$ solution
In case of $H_2{SO}_4$,
$n=2$
Hence, $4.0N{H}_2{SO}_{4}solution\approx 2M{H}_2{SO}_4$ solution.
