PLEASE HELP FAST!! WILL GIVE BRAINLIEST!!
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.

0.1M HCl              [H⁺]=0.1=10⁻¹       pH= - log 10⁻¹ = 1,  pH = 1
0.001M HCl          [H⁺]=0.001=10⁻³       pH= - log 10⁻³ = 3,  pH = 3
0.00001M HCl      [H⁺]=0.00001=10⁻⁵       pH= - log 10⁻⁵ = 5,  pH = 5
Distilled water                                           pH=7


0.00001 NaOH   [OH⁻]=10⁻⁵, [OH⁻][H⁺]=10⁻¹⁴, [H⁺]=10⁻¹⁴/10⁻⁵=10⁻⁹,

0.001 NaOH   [OH⁻]=10⁻³, [OH⁻][H⁺]=10⁻¹⁴, [H⁺]=10⁻¹⁴/10⁻³=10⁻¹¹,
                           pH=11

0.1 NaOH   [OH⁻]=10⁻¹, [OH⁻][H⁺]=10⁻¹⁴, [H⁺]=10⁻¹⁴/10⁻¹=10⁻¹³,

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
