Question

In an acidic solution, ________.

A. The H+ ion concentration is equal to the OH- ion concentration

B. the OH- ion concentration is greater than the H+ ion concentration

C.the OH- ion concentration is less than the H+ ion concentration

D. the H+ ion concentration is less than the OH- ion concentration only if the solution is buffered

Answer 1

An acidic solution will give H+ ions or H3O+ ions when dissolved in water. Whereas, a basic solution will give OH- ions when it is dissolved in water.

Therefore, option A is incorrect. because H+ ions concentration will be equal to OH- ions concentration for neutral solutions.

Option B is incorrect because if OH- ions concentration is greater than H+ ions concentration, then it is a base.

Option C is correct acids have more H+ ions concentration compared to OH- ions concentration.

Option D is incorrect, the pH of the buffer solution depends on the ration of the concentration of base to the concentration of acid. Buffer is not an acidic or basic solution.
