10. Acids and Bases

A solution of NaOH was prepared in a chemistry lab and the pOH was determined to be 9.3. What is the concentration of OH⁻ ions of this basic solution?

Calculate [OH⁻] of a lemon juice solution at 25°C with a [H⁺] = 5.7 × 10⁻⁴ M.

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 × 10^-6 M

Calculate the [H₃O⁺] of each aqueous solution with the following [OH^-]:
