At `30^@C` , the solubility of `Ag_2CO_3(K_(sp)=8xx10^(-12))` would be maximum in 1 litre of

A

`0.05 M Na_(2) CO_(3)`

B

`0.05 M AgNO_(3)`

C

pure water

D

`0.05 M NH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Ag^(+)(aq) + 2NH_(3)(aq) to [Ag(NH_(3))_(2)]^(+)`
The complex formation will decrease `Ag^(+)` ions, hence solubility increases
