Step 1. Write the skeleton equation. The molecular equation is. K2Cr2O7 + H2SO4 +SO2 → K2SO4 + Cr2(SO4)3 +H2O. Strip the equation of all common ions, also H+,OH- and H2O (these come back in during the balancing procedure). K+ + Cr2O2- 7 + H+ + SO2- 4 + SO2 → K+ + SO2- 4 +Cr3+ + SO2- 4 + H2O. The above equation simplifies to. Cr2O2- 7 +SO2.

$$\ce{H2S + K2Cr2O7 + 4H2SO4 -> SO2 + Cr2(SO4)3 + K2SO4 + 5H2O}?\label{rxn:QR2}\tag{R2}$$ 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.

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).

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.
