My question is regarding "solubility and solubility product ".
Our lab had two parts:
a) determine ksp of Ca(OH)2
b) observe how the presence of a commom ion, OH-, affects the
solubility of Ca(OH)2
We had to titrate 0.1M HCl (0.1430 M to be exact) with the
following:
1) Distilled water
2) 0.0125 M NaOH
3) 0.025M NaOH
4) 0.050M NaOH
The volume of naoh used is 25ml
The volume of HCl used was
1) 8 ml 2) 8.20ml 3) 9.10ml 4) 12.70ml respectively
This is what I have to find for all 4 titrations:
a) [OH-]eq (from the data)
b) [OH-]0 solvent
c) [OH-] from Ca(OH)2
d) [Ca2+] from Ca(OH)2
e) Ksp Ca(OH)2
Thank you in advance!

Solubility Product Ksp for Ca(OH)2 is determined in two separate experiments, both at the same temperature. - by titration of hydroxide in a simple saturated solution of Ca(OH)2. - by titration of hydroxide in a 0.01 M CaCl2 solution saturated with Ca(OH)2. Identify which of the following statements is either completely "True" or at least partially "False" (assuming that the activity of each ion is equal to its molar concentration in each instance): a) True False You would expect the value...
