Copper sulphate reacts with NaCN to form...

Copper sulphate reacts with NaCN to form a cyanide complex. Write the balanced equation and find the number of NaCN molecules involved in the equation for one mole of `CuSO_(4)`.

Text Solution

Verified by Experts

The correct Answer is:
`(5)`
`[CuSO_(4)+2NaCN rarr Cu(CN)_(2)+Na_(2)SO_(4)]xx2`
`Cu(CN)_(2)rarr 2CuCN+(CN)_(2)`
`[CuCN+3NaCN rarr Na_(3)[Cu(CN)_(4)]xx2`
`ulbar(2CuSO_(4)+10NaCN rarr 2Na_(3)[Cu(CN)_(4)]+(CN)_(2)+2Na_(2)SO_(4))`
1 mol `CuSO_(4)-=5` mole NaCN
