What happens when potassium dichromate is treated with ferrous sulphate solution in the presence of dilute sulphuric acid ?

Explanation

An acidified solution of `K_(2) CrO_(4)` acts as an oxidising agent, Therefore, When potassium chromate is treated with ferrous sulphate solution in presence of dil `H_(2) SO_(4)` . The reaction is as follows :
`2K_(2) CrO_(4) + 5 H _(2) SO_(4) to 2K_(2) SO_(4) + Cr_(2) (SO_(4))_(3) + 5H_(2) O + 3[O]`
`2FeSO_(4) + H_(2)SO_(4) + [O] to Fe_(2) (SO_(4))_(3) + H_(2)O`
