This question is for a laboratory experiment titled "Determination of the Solubility Product Constant of Calcium Hydroxide" where a saturated solution of Ca(OH)2 in water was titrated with HCl.
Part 1 Data - Saturated Solution of Ca(OH)2 in Water:
Volume of Ca(OH)2 aliquot: 25.00mL
Concentration of standard HCl: 0.1342M
Indicator Used: Bromothymol Blue
Average volume of HCl to reach end point: 7.71mL
a. Write a balanced, net ionic equation for the titration reaction. Use this equation to perform the subsequent calculations.
b. Calculate the [OH-] in the standard Ca(OH)2 solution (using the NET ionic equation).
c. Determine the experimental solubility of the Ca(OH)2 (in mol/L).
d. Determine the experimental Ksp of Ca(OH)2.
Please explain steps/show equations! Thank you.

The solubility constant of silver bromate is 5.5 x 10-5, whereas
the solubility constant of calcium sulfate is 2.4 x 10-5, while
they are close to the same solubility due to their exponents being
the same, calcium sulfate has a smaller leading number and so it is
less soluble than silver bromate. What is more soluble, magnesium
hydroxide or magnesium carbonate?

± Introduction to Solubility and the Solubility Product
Constant
Learning Goal:
To learn how to calculate the solubility from Kspand
vice versa.
Consider the following equilibrium between a solid salt and its
dissolved form (ions) in a saturated solution:
CaF2(s)⇌Ca2+(aq)+2F−(aq)
At equilibrium, the ion concentrations remain constant because the
rate of dissolution of solid CaF2 equals the rate of the ion
crystallization. The equilibrium constant for the dissolution
reaction is
Ksp=[Ca2+][F−]2
Ksp is called the solubility product and can be...
