`KI` and ` CuSO_4` solution when mixed give .

A

`Cu l_2 + K_2SO_4`

B

`Cu_2I_2 + K_2SO_4`

C

`K_2SO_4 + CU_2I_2 +I_2`

D

`K_2SO_4 + CuI_2I_2`

Text Solution

Verified by Experts

The correct Answer is:
C
First cupric iodide is formed which decomposes to give white cuprous iodide and ioding . This happens because iodide is a strong reducing agent :
`{:(CuSO_(4)+2KI rarr CuI_(2)+K_(2)SO_(4)xx2),(2CuI_(2) rarr Cu_(2)I_(2)+I_(2)),(bar(2CuSO_(4)+4KI rarr Cu_(2)I_(2)+I_(2)+2K_(2)SO_(4))):}`
