What volume of 2

N

{\mathrm{K}_2}\mathrm{C}{\mathrm{r}_2}{\mathrm{O}_7}

solution is required to oxidise 0.81 g of

{\mathrm{H}_2}\mathrm{S}

in acidic medium?

View answer and explanation

Correct option: B

23.8 mL

Option B (23.8 mL) is correct because it is the volume of K2Cr2O7 solution required to oxidize 0.81 g of H2S, based on stoichiometry and normality.
