Reaction of potassium chromate and CuSO(...

Reaction of potassium chromate and `CuSO_(4)` in aqueous solution produces:

`CuCrO_(4)` only

`Cu_(5)[CrO_(4)]_(2)` only

`CuCr_(2)O_(7)` only

Both `CuCrO_(4)` and `Cu_(2)Cr_(2)O_(7)`.

Text Solution

Verified by Experts

The correct Answer is:

Aqueous solution of `CuSO_(4)` is acidic in nature, it converts some `CuCrO_(4)` to `CuCr_(2)O_(7)`..

CuSO_(4) solution is

A white substance (A) reacts with dilute H_(2)SO_(4) to produce a colourless suffocating gas (B) and a colourless solution (C )/ The reaction of gas (B) with potassium iodate and starch solution produce a blue colour solution. Aqueous Solution of (A) gives a white precipitate with BaCl_(2) solution which is soluble in dilute HCl . Addition of aqueous NH_(3) or NaOH to (C ) produced first a precipitate which dissolves in excess of the respective reagent to poduced a clear solution. Similarly addition of excess of potassium ferrocyanide to (C ) produced a precipitate (D) which also dissolves in aqeous NaOH giving a clear solution. Identify (A),(B),(C ) and (D ).
