If a sample of a certain solution is determined to have a pH of 11.8 11.8 , what is the concentration of [ H 3 O + ] [H3O+] in the solution

Question

Submit your answer in scientific notation and round off the significand (first number) of your answer to two decimal places.

Answer 1

pH = -log [H₃O⁺]

[H₃O⁺] = 1x10^-11.8

[H₃O⁺] = 1.58x10^-12 M
