chloride, sodium hypochlorite and sodium hydroxide. After the equation is in molecular form, balance by trial if necessary.
Redox pair Bi3+ / BiO3- and ClO-/Cl-
Alkaline condition
Bi3+ + 6 OH- => BiO3- + 3 H2O + 2 e-
ClO- + H2O +2 e- => Cl- + 2 OH-
Addition
Bi3+ + 4 OH- + ClO- => BiO3- + Cl- + 2 H2O
Add Cl- + Na+
BiCl3 + 4 NaOH + NaClO => NaBiO3 + 4 NaCl + 2 H2O
