Homework Help: Chemistry - Ksp

Posted by Farah on Monday, April 25, 2011 at 12:40am.

i did an experiment where we titrated HCl on calcium hydroxide, and now i am confused with the calculations, i do not know if i am correct, so please help me out...

Trial One
volume of HCl used - 11.20mL
concentration of HCl - 0.04mol/L
so to get moles of HCl i used M= CV
is that correct?

than to get moles of OH- in the solution, i did (M*V)/ 10mL(vlume of calcium hydroxide)
is that correct?

but then how do i find out the concentration of [OH-] and [Ca2+] at equilibrium. when i a supposed to even find out the Ksp int he same experiment?
