• question_answer 70) Assertion (A): In the reaction between potassium permanganate and potassium iodide, permanganate ions act as oxidising agent.Reason (R): Oxidation state of manganese changes from +2 to +7 during the reaction.(a) Both A and R are true and R is the correct explanation of the A.                                    (b)Both A and R are true but R is not the correct explanation of the A.(c) A is true but R is false.(d) Both A and R are false.

(c) Permanganate oxidises iodide salts to iodine in acid medium, the oxidation state of manages changes from (+7) to (+2) in this reaction. $2MnO_{4}^{-}+{{101}^{-}}+16{{H}^{+}}\to 2\overset{+2}{\mathop{M{{n}^{2+}}}}\,+5{{I}_{2}}+8{{H}_{2}}O$
