How Ksp Is Calculated

Next we write out the expression for Ksp , then “plug in” the concentrations to obtain the value for Ksp. Let’s do an example: The solubility of Ag2CrO4 in water is 1.31 x 10-4 moles/L. Calculate the value of Ksp . Using mole ratios, the [Ag+] will go up by (2 x 1.31 x 10-4 moles/L) = 2.62 x 10-4 moles/L.

What is the KSP of KHC4H4O6?

The literature Ksp value for KHC4H4O6 is 3.8 x 10-4 at 291.15K.

Does KSP have a unit?

The K s p value does not have any units because the molar concentrations of the reactants and products are different for each equation.
