Q. 100 cc of $ 0.6\text{ }N\text{ }{{H}_{2}}S{{O}_{4}} $ and 200 cc of $ 0.3\text{ }N\text{ }HCl $ were mixed together. The normality of the solution will be

Solution:

Normality of the mixed solution $ =\frac{{{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}}{{{V}_{1}}+{{V}_{2}}}=\frac{0.6\times \frac{100}{1000}+0.3\times \frac{200}{1000}}{\frac{100+200}{1000}} $ $ =\frac{0.6\times 0.1+0.3\times 0.2}{0.3} $ $ =\frac{0.06+0.06}{0.3}=\frac{0.12}{0.3}=0.4N $
