2 Cr(OH)3 + 2 Na2CO3 + 3 NaClO → 2 Na2CrO4 + 3 NaCl + 2 CO2 + 3 H2O
This is an acid-base reaction (neutralization): Cr(OH)3 is an acid, Na2CO3 is a base.
This is an oxidation-reduction (redox) reaction:
3 ClI + 6 e- → 3 Cl-I (reduction)
2 CrIII - 6 e- → 2 CrVI (oxidation)
NaClO is an oxidizing agent, Cr(OH)3 is a reducing agent.
Reactants:
- Cr(OH)3 – Chromium(3+) hydroxide
- Na2CO3 – Sodium carbonate
- NaClO – Sodium hypochlorite
