Question
For the dissolving of Mn(OH)2, the equilibrium constant expression, Ksp, is Question 7Select one:Ksp = [Mn2+] [OH-]2 / [Mn(OH)2]Ksp = [Mn2+] [OH-] / [Mn(OH)2]Ksp = [Mn(OH)2] / ([Mn2+] [OH-] 2) Ksp = [Mn2+] [OH-]2Ksp = [Mn2+] [OH-]
Solution
The correct answer is Ksp = [Mn2+] [OH-]^2. This is because the solubility product constant, Ksp, is calculated by multiplying the concentrations of the ions in the solution. In the case of Mn(OH)2, it dissociates into Mn2+ and 2 OH- ions. Therefore, the concentration of OH- ions is squared in the Ksp expression.
