Explain the catalytic action of Iron(III) in the reaction between `I a – InterviewSolution

InterviewSolution

1.	Explain the catalytic action of Iron(III) in the reaction between `I and S_(2)O_(8)^(2-)` ions.
Answer» Transition metal ions can change their oxidation states and become more effective catalysts. Iron (III) Catalyses the reaction between iodide and per sulphate ions `2I^(-)+S_(2)O_(8)^(-2)overset(Fe^(+3))rarrI_(2)+2SO_(4)^(-2)` Catalytic action explained as follows `2Fe^(+3)+2I^(-)rarr2Fe^(+2)+I_(2)` `2Fe^(+2)+S_(2)O_(8)^(-2)rarr2Fe^(+3)+2SO_(4)^(-2)`
