The pH of a liquid is a measure of how acidic or basic it is. The concentration of hydrogen ions in a liquid islabeled [H+]. Use the formula pH = –log[H+] to find the pH level, to the nearest tenth, of a liquid with [H+] about 7.8 x 10^-12.

-log[H+] = ph

-log[7.8 x 10^-12] = 11.1

pH  = - log (7.8 x 10^-12)  ≈    11.1
