Example #1: Determine the K sp of silver bromide, given that its molar solubility is 5.71 x 10¯ 7 moles per liter. Solution: 1) When AgBr dissolves, it dissociates like this: AgBr(s) ⇌ Ag + (aq) + Br¯(aq). 2) The K sp expression is: K sp = [Ag +] [Br¯]. 3) There is a 1:1 molar ratio between the AgBr that dissolves and Ag + that is in solution.
