Solid silver acetate is slowly added to 75.0 mL of a 0.0383 M sodium bromide solution
Solid silver acetate is slowly added to 75.0 mL of a 0.0383 M sodium bromide solution. The concentration of silver ion required to just initiate precipitation is _______ M.
Homework Answers
Ag+(aq) + Br-(aq) ----> AgBr(s)
Ksp of AgBr = [Ag+][Br-]
Ksp of AgBr = 4.1*10^-13
[Ag+] = ?
[Br-] = 0.0383 M
4.1*10^-13 = x* 0.0383
x = 1.07*10^-11
concentration of Ag+ required to initiate preipitate = 1.07*10^-11 M
