Write the balanced equation and solubility product expression for the solubility equilibrium of Mn3(PO4)2: i thought the answer was
Mn3(PO4)2 (s) = Mn^2+(aq) + (PO4)2 ^3- (aq) but that's not right. then for the Ksp expression i thought it was [Mn^2+] [PO4]^2
The balanced equation for the solubility equilibrium of Mn3(PO4)2 is:
Mn3(PO4)2 (s) ⇌ 3 Mn^2+ (aq) + 2 (PO4)^3- (aq)
However, your solubility product expression is not correct. The correct solubility product expression (Ksp) for Mn3(PO4)2 is:
Ksp = [Mn^2+]^3 * [(PO4)^3-]^2
It is important to note that the concentrations of the ions are raised to their respective stoichiometric coefficients in the solubility product expression.
To write the balanced equation for the solubility equilibrium of Mn3(PO4)2, you need to consider the dissociation of the compound into its respective ions. In this case, Mn3(PO4)2 dissociates into Mn^2+ (aq) and (PO4)^3- (aq) ions:
Mn3(PO4)2 (s) ⇌ 3Mn^2+ (aq) + 2(PO4)^3- (aq)
Please note that the coefficients in front of each species represent the stoichiometric ratio for the reaction.
Next, let's write the solubility product expression (Ksp) for this equilibrium. The solubility product expression is the mathematical representation of the equilibrium constant for the dissolution/dissociation of a sparingly soluble compound.
The Ksp expression can be written using the concentration of Mn^2+ (aq) and (PO4)^3- (aq) ions raised to the power of their respective stoichiometric coefficients:
Ksp = [Mn^2+]^3 * [(PO4)^3-]^2
Therefore, the correct solubility product expression for Mn3(PO4)2 is [Mn^2+]^3 * [(PO4)^3-]^2.
It is important to note that the solubility product constant (Ksp) is a constant value characteristic of a specific compound at a particular temperature. By comparing the values of ion concentrations with the Ksp value, you can determine whether the compound will precipitate or remain dissolved in a solution.
Mn3(PO4)2 ==> 3Mn^+2 + 2PO4^-3
Ksp = (Mn^+2)^3(PO4^-3)^2
