Homework Statement
Find pH of solution A and that of Solution C with the following information below:
Solution A:50ml of 0.100 M solution of weak monoprotic acid HX
Solution B: 0.0500M solution of salt NaX. It has a pH of 10.02
Solution C: made by adding 15.0m; of 0.250 M KOH to solution A
Homework Equations
Ka for monoprotic acid is 7.2 x 10^-4, Ka=[H+] [anion]. Anion= x
1/2log(Ka)=[H+]
The Attempt at a Solution
i try to find [H+] which i did was 1/2log(Ka)=
1/2log (7.2 x 10^-4) = 0.0268
or I find the M of [H+] in solution A
and i found 0.005M of HX
