A chemist is performing an experiment with hydrofluoric acid that requires the use of sophisticated pH equipment, including meters, test strips, and litmus paper. In order to calculate the hydrogen ion concentration of the hydrofluoric acid solution, the chemist determines that the hydroxide ion concentration of the HF solution is exactly 1.5 x 10-5M. What is the hydrogen ion concentration of the chemist's solution

Therefore, the hydrogen ion concentration of the hydrofluoric acid solution = 6.67 × 10-¹⁰ M

Explanation:

The product of hydroxide ion concentration and the hydrogen ion concentration of a solution is given by the ionic product of pure water and is constant for all solutions.

The ionic product of water, Kw = [H+] × [OH-] = 1 × 10-¹⁴ M²

Where [H+] is the hydrogen ion concentration; [OH-] is the hydroxide ion concentration

For the hydrofluoric acid solution, the hydroxide ion concentration, [OH-] = 1.5 × 10-⁵ M

Since [H+] × [OH-] = 1 × 10-¹⁴

[H+] = 1 × 10-¹⁴ / [OH-]

[H+] = 1 × 10-¹⁴ M² / 1.5 × 10-⁵ M

[H+] = 6.67 × 10-¹⁰ M

Therefore, the hydrogen ion concentration of the hydrofluoric acid solution is 6.67 × 10-¹⁰ M

it is a solid
