pH

pH = - log[H+]                [H+] = 10-pH






Calculate the pH for each [H+] given below:

[H+] = 0.00025; pH = 3.60

[H+] = 1.0 x 10-7; pH = 7.00

[H+] = 2.3 x 10-3; pH = 2.64

[H+] = 7.6 x 10-12; pH = 11.12

Determine the [H+] from the pH:

pH = 7.4; [H+] = 3.98 x 10-8

pH = 2.8; [H+] = 0.00158

pH = 12.7; [H+] = 2.0 x 10-13

pH = 4.5; [H+] = 0.0000316
