In which of the following solvents will `AgBr` has highest solubility?

Options

A. `10^(-3) M `NaBr
B. `10^(-3) M NH_(4)OH`
C. pure water
D. `10^(-3)` M HBr

Answer

2

Explanation

With ammonia , `Ag^(+)` forms a complex of the type, `[Ag(NH_(3))_(2)]^(+)`. This increases its solubility compared to pure water . In NaBr and HBr, AgBr will encounter a common ion effect, which would reduce its solubility compared to pure water .
