    Since H2SO4 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.

    In dilution the ions of weak electrolyte is free to move so the conductivity is increase. But in strong electrolyte molar conductivity is decrease because the ions is much more free.

    3Thank You
