what happens when H2O2 reacts with KI?
Dear student!
The hydrogen peroxide undergo catalytic decomposition because iodide ion is not consumed by the peroxide and the product obtained is rapidly formed water molecules and oxygen gas. Here KI acts as a catalyst.
The reaction is :
2H2O2 ---KI--->2H2O + O2 + heat.
The detailed reaction is :
H2O2 + I- --> H2O + OI-(aq.)
H2O2 +OI- ---> H2O + O2 + I- (aq.)
