hey guys ur answer is below with explaintion
We interrogate the equilibrium reaction:
Ag++Br−→AgBr(s)⏐↓
Explanation:
We have been given the thermodynamic equilibrium constant for this reaction, i.e.:
Ksp=[Ag+][Br−]=4×10−13.
Ksp is the so-called solubility product, which have been measured for a host of inorganic salts. And so we simply substitute in [Ag+], and solve for [Br−]............
[Br−]=Ksp[Ag+]=4×10−131×10−6=4.0×10−7⋅mol⋅L−1
And thus, should [Ag+]>4.0×10−7⋅mol⋅L−1, a precipitate of creamy yellow AgBr salt will be observed.
