If H2S gas is passed through a Solution of K2Cr2O7, what will be the color of the solution? (Detailed Information Required)

Question

Vikas TU · Answer

Dear student

The reaction is

3H2S + K2Cr2O7 + 4H2SO4 → 3S + Cr2(SO4)3 + K2SO3 + 7H2O

Hydrogen sulfide react with potassium dichromate and sulfuric acid to produce sulfur, chromium(III) sulfate, potassium sulfate and water. Hydrogen sulfide - saturated solution. Sulfuric acid - diluted solution
Milkness in the in the solution is due to element S in solution . But the green colour appears because of CrCl3 in solution
