A reaction in which the same species is simultaneously oxidised as well as reduced is called a disproportionation reaction
(ii)

I_{2} 0 \to I^{-} - 1 + I O_{3} + 5

(iii)

3 C l_{2} 0 + 6 N a O H \to 5 N a Cl - 1 + N a Cl + 5 O_{3} + 3 H_{2} O

(iv)

P_{4} 0 + 3 N a O H + 3 H_{2} O \to 3 N a H_{2} P + 1 O_{4} + P - 3 H_{3}
