Aqueous solution of metallic nitrate X r...

Aqueous solution of metallic nitrate X reacts with `NH_4OH` to form Y which dissolves in excess `NH_4OH`. The resulting complex is reduced by acetaldehyde to deposit the metal. X and Y, respectively, are

A

`Cs(NO_3) and CsOH`

B

`Zn(NO_3)_2 and ZnO`

C

`AgNO_3 and Ag_2O`

D

`Mg(NO_3)_2 and Mg(OH)_2`

Text Solution

Verified by Experts

The correct Answer is:
C
`AgNO_3 + NH_4OH to AgOH underset("(excess)") overset(NH_4OH)to [Ag(NH_3)_2]^(+0)`
Tollen.s reagent `+ R - CHO to R - COOH`
