How to calculate the pH of this solution? 0.002 mol of solid calcium hydroxide is added in 250 mL solution of hydrochloric acid with the concentration of 0.004 mol / L.
1 Answer
Well, first we interrogate the stoichiometric equation....
Explanation:
And then we determine equivalent quantities of (i),
...and (ii) hydrochloric acid....
...and given that calcium hydroxide is a dibase....we gots
Now............
But
Note that I have assumed (reasonably) that all the calcium hydroxide has gone up into solution...I am not going to consider the aqueous solubility of calcium hydroxide....
