$K_{sp} = [Cu^+][Br^-]$

Work Step by Step

1. Identify the ions, and write the equilibrium reaction for the dissociation of the salt $(CuBr)$: - $Cu^+$ and $Br^-$ - $CuBr(s) \lt -- \gt Cu^+(aq) + Br^-(aq)$ 2. Balance the reaction: - $1 CuBr(s) \lt -- \gt 1Cu^+(aq) + 1Br^-(aq)$ 3. Write the $K_{sp}$ expression: - Multiply the concentrations of the ions. - The balancing coefficients are used to determine the exponents of the concentrations. - $K_{sp} = [Cu^+]^1 \times [Br^-]^1$
