10. Acids and Bases

In an acidic solution, how does the concentration of H₃O⁺ compare to the concentration of OH⁻?

If a base is added to pure water, why does the [H₃O⁺] decrease?

Calculate the [H₃O⁺] of each aqueous solution with the following [OH⁻]: d. bile, 2.5 x 10⁻⁶ M

Calculate the [H₃O⁺] of each aqueous solution with the following [OH⁻]: a. baking soda, 1.0 x 10⁻⁶ M

State whether each of the following is acidic, basic, or neutral: c. drain cleaner, pH 11.2

Why does a neutral solution have a pH of 7.0?

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 x 10⁻⁴ M

Calculate the pH of each solution given the following: c. [OH⁻] = 1 x 10⁻⁵ M

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 x 10⁻² M. What is the pH of the stomach fluid?

Determine the pH for the following solutions: (10.6) c. [H₃O⁺] = 0.0001M

Solution A has a pH of 4.0, and solution B has a pH of 6.0. (10.6) a. Which solution is more acidic?

Solution X has a pH of 9.0, and solution Y has a pH of 7.0. (10.6) a. Which solution is more acidic?

One of the most acidic lakes in the United States is Little Echo Pond in the Adirondacks in New York. Recently, this lake had a pH of 4.2, well below the recommended pH of 6.5. (10.6, 10.7) a. What are the [H₃O⁺] and [OH⁻] of Little Echo Pond?
