When cupric sulphate solution is added with 'X' it produced a deep blue coloured soluble complex 'Y' . The primary and secondary valencies of copper in 'Y' are `:`

A

2,2

B

1,4

C

D

4,4

Text Solution

Verified by Experts

The correct Answer is:
3
`2Cu^(2+)+SO_(4)^(2-)+2NH_(3)+2H_(2)OrarrCu(OH)_(2).CuSO_(4)darr+2NH_(4)^(+)`
`Cu(OH)_(2).CuSO_(4)+8NH_(3)rarr2[Cu(NH_(3))_(4)]^(2+)+SO_(4)^(-2)+2OH^(-1)`
