$$\ce{H2S + K2Cr2O7 + 4H2SO4 -> SO2 + Cr2(SO4)3 + K2SO4 + 5H2O}?\label{rxn:QR2}\tag{R2}$$ The reaction seems stoichiometrically plausible, yet likely requires highly concentrated oxidants. I know \eqref{rxn:QR1} happens at low concentration of $\ce{H2SO4}$. Maybe using highly concentrated $\ce{H2SO4}$ would do the work for \eqref{rxn:QR2}. What.

The hydrogen atoms are already balanced, so we don't need to make any changes. The equation now looks like this: K2Cr2O7 + H2SO4 ---> K2SO4 + Cr2(SO4)3 + H2O + 2O2 Answer 3. Finally, we need to balance the number of potassium and sulfate ions. On the left side, we have 2 potassium ions from K2Cr2O7 and 1 sulfate ion from H2SO4.

This reaction can be represented by the following equation: K2Cr2O7 + H2SO4 → H2CrO4 + K2SO4. Chromic acid is a strong oxidizing agent and plays a crucial role in the subsequent steps of the reaction. Oxidation of Sulfuric Acid: In the presence of chromic acid, sulfuric acid gets oxidized to form sulfur trioxide (SO3).
