(a) Write ionic equations for the reaction of acidified potassium permanganate with following: (i) Oxalic acid, (ii) H_2 S,(iii) Sulphite ion.(b ) Describe the reactivity of actinoids.

Answer»

SOLUTION :(a) (i) ` 2MnO_(4)^(-) + 16 H^++ 5C_2 O_(4)^(2-)to2Mn^(2+)+8H_2O+10 CO_2`
`(ii)2MnO_(4)^(-)+ 5 S^(2-)to 2Mn^(2 +)+8H_2 O + 5S `
`(III)2MnO_4^(-)+ 6H^(+)+5SO_(3)^(2-)to 2Mn^(2+) +3H_2 O +5SO_(4)^(2-)`
(b) ACTINOIDSARE HIGHLY reactivemetalsin the finelydividedstatedueto lowionisationenthalpies
