When K_2CrO_4 is added to CuSO_4 solution, there is formation of CuCrO_4 as wel as CuCr_2O_7. Formation of CuCr_2O_7 is due to

Answer»

BASIC nature of `CuSO_4` solution
ACIDIC nature of `CuSO_4` solution
`CuSO_4` oxidizes `CrO_4^(-2)` to `Cr_(2)O_(7)^(-2)`
This is the typical property of `CuSO_4`

Solution :Due to Acidic nature of `CuSO_4 , CrO_(4)^(-2)OVERSET(H^+)rarr Cr_2O_7^(-2)`
