Answer to for trials 2 and 3, the ksp of ca(oh)2 was 52 times 10-6 and 48 times 10-6 respectively what is the average ksp of ca. Purpose: to determine the solubility product (ksp) of calcium hydroxide (aqueous) introduction: ksp is how much a salt dissociates, so a greater ksp would mean more dissociation calcium hydroxide dissolving in water yields calcium ion and 2 hydroxide ions, thus the ksp would be: ksp = (ca)(oh)^2 to make the calcium hydroxide we just add water.
