Homework Help: pH
Posted by Christine on .
what's the pH of
the acid HCl with concentration of .15?
the acid HC2H3O2 with concentration of .15?
I figured out the pH of HCl, but I'm still not sure how to find the other one...
What is the dissociation constant for acetic acid?
pH= -log sqrt (.15 k) check that.
acetic acid being weak is ionized in less quantity in the solution.its dissociation constant is taken to be 0.0000176 By the given problem [H+]=root over(dissociation constant*given molarity) finally the pH obtained is 2.789198037
