Best Answer

There is no real "net ionic" equation, as KI is a catalyst that decomposes H2O2.

The "slow step" is H2O2 + I- --> OI- + H2O

The "fast step" is H2O2 + OI- --> H2O + I- O2

The overall is: 2 H2O2 --> 2H2O + O2

Copper(II) ions oxidise iodide ions to iodine, and in the process are themselves reduced to copper(I) iodide:

2Cu2+(aq) + 4I-(aq) --> 2CuI(s) + I2(aq)

The K+ and SO42- ions are spectator ions, appearing unchanged on both sides of the equation. They can be ignored to leave the above as the net ionic equation.

2I- --> I2 + 2e-

H2O2 + 2H+ 2e- --> 2H2O

Overall:

2I- + H2O2 + 2H+ --> I2 + 2H2O

With excess iodide the I2 produced will complex with I- to produce I3- in solution.

Why is KI a catalyst for H202 decomposition but KBr and KCl aren't?

The mechanism of catalysis involves the I- ion only. The mechanism is: H2O2 + I- --> IO- + H2O H2O2 + IO- --> I- H2O O2 Second step regenerates the I- ion (thus acts as a catalyst). This reaction is first order wrt to both H2O2 and I-. Notably exothermic reaction. Must be in a medium which allows formation of I-, ie dissociation of KI. Water is a wonderful example.

What is the balanced chemical equation for HCL and KI?

There is no reaction, because all product ( if reaction goes) would be soluble. so : H+ + Cl- + K+ + I- = H+ + Cl- + K+ + I- and than all of them dare present as a ions only.

Why sulfuric acid is not used while reaction of alcohol with KI?

In the presence of sulphuric acid (H2SO4), KI produces HI Since is an oxidizing agent, it oxidizes HI (produced in the reaction to I2). As a result, the reaction between alcohol and HI to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used during the reaction of alcohols with KI. Instead, a non-oxidizing acid such as H3PO4 is used.
