A) \[4.0\text{ }N\text{ }{{H}_{2}}S{{O}_{4}}\]
B) \[0.5\text{ }N\text{ }{{H}_{2}}S{{O}_{4}}\]
C) \[1\text{ }N\text{ }{{H}_{2}}S{{O}_{4}}\]
D) \[2\text{ }N\text{ }{{H}_{2}}S{{O}_{4}}\]
Correct Answer: A
Solution :
Relationship between normality and molar concentration is Normality \[=n\times \]molarity (M) where,\[n=\]the number of moles of \[{{\text{H}}^{\text{+}}}\]per mole of the compound that a solute is capable of releasing [acid] on reacting with base. In case of HCl, \[n=1\] Hence, 2 N HCl solution\[\approx \text{2M}\,\text{HCl}\] solution In case of \[{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\text{,}\] \[n=2\] Hence,\[\text{4}\text{.0 N }{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\] solution \[\approx \text{2}\,\text{M}\,{{\text{H}}_{\text{2}}}\text{S}{{\text{O}}_{\text{4}}}\] solution.
