Urea reacts with water to form A which will decompose to form B. B when passed through `Cu^(2+)`(aq), deep blue color solution C is formed. What is the formula of C from the following?

A

`CuSO_4`

B

`[Cu(NH_3)_4]^(2+)`

C

`Cu(OH)_2`

D

`CuCO_3. Cu(OH)_2`

Text Solution

Verified by Experts

The correct Answer is:
B
`NH_2CONH_2 + H_2O to CO_2 + underset((A))(NH_4OH)`
`NH_4 OH overset(Delta)to underset((B))(NH_3) + H_2O`
`Cu^(+2)(aq) + 4NH_3 to underset(("deep blue")) underset(( C))([Cu(NH_3)_4]^(+2))`
