C12H22O11 (aq) + 24 H2SO4 (aq) → 24 SO2 (aq) + 12 CO2 (g) + 35 H2O (l)
This is an oxidation-reduction (redox) reaction:
12 C0 - 48 e- → 12 CIV (oxidation)
24 SVI + 48 e- → 24 SIV (reduction)
C12H22O11 is a reducing agent, H2SO4 is an oxidizing agent.
This is a gas evolution reaction, CO2 is the formed gas.
