Answer 2

Dear Student,

● Answer -

(c) Ferric sulphate

● Explaination -

Acidified potassium chromate is strong oxidizing agent. It oxidises the corresponding substance by itself getting reduced (Cr4+ → Cr3+).

Ferric sulphate has iron in oxidation state +3 which is max OS it's capable of.

Therefore, acidified potassium dichromate can not further oxidize ferric sulphate.

Hope you understand. Thanks for asking question.
