... Now convert to a basic solution. Add 4 OH− to both sides of the equation. The 4 OH− will react with the 4 H+ on the product side to give 4 H2O. After this step, cancel identical species on both sides (2 H2O). Applying these steps gives: 4 OH− + 2 Cl2 → 2 Cl− + 2 OCl− + 2 H2O, which can be further si ...
