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.
