Question

100 ml of 0.3 N HCl solution were mixed with 200 ml of 0.6 N H2SO4 solution. the normality of final solution is

Answer 1

$\text{Net Normality}\\ =\dfrac{\text{Number of milliequivalents}}{\text{Millilitres of water}}\\ \\ =\dfrac{100\cdot 0.3+200 \cdot 0.6}{100+200}\\ =\dfrac{150}{300}=0.5N$
