Question

An aqueous solution has a hydrogen ion concentration of m. What is the hydroxide ion concentration in this solution? 1.1x10⁻4 concentration = m. Is this solution acidic, basic, or neutral? a. 1.1x10⁻4 M, acidic b. 1.1x10⁴ M, basic c. 1.0x10⁻14 M, neutral d. 1.0x10¹4 M, neutral

Answer 1

The hydroxide ion concentration of a solution with a hydrogen ion concentration of 1.1x10⁻⁴ M is 9.09x10⁻¹¹ M, and the solution is acidic.

Step-by-step explanation:

An aqueous solution with a hydrogen ion concentration of 1.1x10⁻⁴ M yields the hydroxide ion concentration by using the water ion product: [H₃O+] x [OH⁻] = 1.0 x 10⁻¹⁴. Thus, the hydroxide concentration can be found by dividing 1.0 x 10⁻¹⁴ by the given hydrogen ion concentration:

[OH⁻] = 1.0 x 10⁻¹⁴ M / 1.1x10⁻⁴ M = 9.09 x 10⁻¹¹ M. Considering the original question may contain a typo in the options provided for hydroxide ion concentration, the closest correct value is 9.09x10⁻¹¹ M, which indicates that the solution is acidic because the hydrogen ion concentration is greater than 1.0 x 10⁻⁷ M.
