The molar solubility of silver sulfate in a 0.142 M ammonium sulfate solution is _______ M
The Ksp of silver sulfate is 1.4×10-5
Ag2SO4 = 2Ag+(aq) + SO42-(aq)
0.142 M ammonium sulfate has 0.142 M sulfate
Ksp = [Ag+]2[SO42-]
1.4 x 10-5 = [Ag+]2 x 0.142
[Ag+]2 = 9.85 x 10-5
[Ag+] = 0.0099 M
Since 2 moles of silver is got from each silver sulphate the solubility of silver sulpate in 0.142 M ammonium sulfate is 0.0099/2 = 0.00496 M
