Question
If “X” moles of Ag2Cr2O7 are dissolved in water to produce a saturated solution then Ksp will be
Solution
The solubility product constant, Ksp, is a measure of how much of a compound can dissolve in a solution. It is determined experimentally and is specific to the compound and the temperature of the solution.
For the compound Ag2Cr2O7, the dissolution reaction in water can be written as:
Ag2Cr2O7(s) ⇌ 2Ag+(aq) + Cr2O7^2-(aq)
The expression for the solubility product constant is:
Ksp = [Ag+]^2 * [Cr2O7^2-]
If "X" moles of Ag2Cr2O7 are dissolved in water to produce a saturated solution, then the concentrations of Ag+ and Cr2O7^2- in the solution are both "X".
Therefore, the Ksp for this solution would be:
Ksp = X^2 * X = X^3
So, the Ksp will be X^3 for a saturated solution of Ag2Cr2O7 where "X" moles of the compound are dissolved.
