Hi to all,
I'm in this problem:
I've got to prepare a solution of Ca(OH)2 with pH=13.2 .
On Perry I read that the solubility value of Ca(OH)2 at T=25°C is 1.65 g/L, so a solution with water and Calcium Hydroxide cannot reach pH=13.2.
So I was suggested to prepare the mixture in the following manner:
distilled water + 4g Ca(Oh)2 + 1g Na2SO4 + 1g NaCl + 1g NaNO3 .
I'd like to know if this solution is correct and why.
Thank you very much,
Caccioppoli
