If you know the [OH^-], how can you determine the pH of a solution?

Calculate the pH of each solution given the following:

f. [OH^-] = 8.2 × 10^-4 M

Calculate the pH of each solution given the following:

c. [OH^-] = 1 × 10^-5 M

Complete the following table:

What is the difference between H⁺ and H₃O⁺?

When food enters the stomach, HCl is released and the [H₃O⁺] of the stomach fluid rises to 4 × 10^–2 M. What is the pH of the stomach fluid?

Determine the pH for the following solutions:

c. [H₃O⁺] = 0.0001 M

Solution A has a pH of 4.0, and solution B has a pH of 6.0.

a. Which solution is more acidic?
