Using the Equilibrium Solubility Constant

Some carbonate compounds have limited solubility.
MCO3(s) M²+ (aq) + CO3²- (aq)
The solubility constant Ksp for a carbonate compound MCO3, Ksp = 2.5E-7.
A saturated solution of the compound MCO3, is made.
Calculate the concentration of the ions M²+ (aq) and CO32-(aq) in the saturated solution (check the stoichiometry, the
ions will have the same concentration).
Give your answer to three significant figures, using the exponential format, example enter 0.0000382 as 3.82e-5
with no gaps and the -ve e if power is -ve.

Answer:

The solubility product constant (Ksp) describes the equilibrium between a solid and its constituent ions in a solution. The value of the constant identifies the degree to which the compound can dissociate in water. The higher the Ksp, the more soluble the compound is.
