Default I hate Chemistry.

Well, I was getting a C, now I'll be happy to be passing.

anyways the point of this......

The final question on my test today I want to see if any of you can do it.

Ca(OH)2 a strong base is only slightly soluable in water. You dissolved just enough solid Ca(OH)2 in 30degree C water to form a clear solution. 100 mL of this solution was pipetted out and transfered to a 250 mL erklenmyer flask. It was titrated against .05 M (molarity) HCl solution ot the Phenolphthalein end point. The titration took 48.80 mL of the solution find the following.......

(a) a balanced chemical equation for the reaction of Ca(OH)2 and HCl

(b) The molarity of the Ca(OH)2

(c) The soluablity of Ca(OH)2 in 30C water in grams of Ca(OH)2 per 100 mL of solution.
