When 10 mL of 0.2 M of $\mathrm{H}_2 \mathrm{SO}_4$ is added to 90 mL of $\mathrm{H}_2 \mathrm{O}$,

Question

When 10 mL of 0.2 M of $\mathrm{H}_2 \mathrm{SO}_4$ is added to 90 mL of $\mathrm{H}_2 \mathrm{O}$, the concentration of $\mathrm{H}_2 \mathrm{SO}_4$ is.

Professor PC Thomas Classes · Answer

Diluted molarity $M = \frac{10 	imes 0.2}{100} = 0.02	ext{ M}$. Normality for diprotic $H_2SO_4$ is $0.04	ext{ N}$.
