Will give for the acids, use the formula ph = -log[h+]. (because hcl has 1 h+ ion per formula unit, [h+] equals the molarity.) for water, us what you know about the ph of neutral solutions. for the bases, examine and extend the pattern.

The pH of a solution shows how acidic or basic the solution is.

We are required to obtain the pH of solutions listed, from left to right, we have;

1) pH = -log(0.1 M) = 1

2) pH = - log(0.001 M) = 3

3) pH = -log (0.00001 M) = 5

4) Distilled water is neutral hence it has a pH of 7

5) pOH = -log(0.00001 M) = 5

pH = 14 - 5 = 9

6) pOH  = - log(0.001 M) = 3

pH = 14 - 3 = 11

7) pOH = - log(0.1 M) = 1

pH = 14 -1 = 13
