Question

Which description correctly characterizes the acidity or basicity of a solution? The higher the pH is, the more the hydroxide ion concentration decreases and the more acidic the solution becomes. The higher the pH is, the more the hydroxide ion concentration increases and the more basic the solution becomes. The lower the pH is, the more the hydronium ion concentration decreases and the more acidic the solution becomes. The lower the pH is, the more the hydronium ion concentration increases and the more basic the solution becomes.

Answer 1

Answer:

The higher the pH is, the more the hydroxide ion concentration increases and the more basic the solution becomes.

Explanation:

• When the pH of a solution is less than 7, then solution is called acidic and as the pH decreases the concentration of Hydronium ion increases.
• When the pH is about 7, then the  solution is said to be neutral. On the other hand, when  the pH is greater than 7, the solution is is said to be basic and as the pH increases the concentration of Hydroxide ions increases.
• Therefore, An acidic solution has a higher concentration of hydrogen ions compared to the concentration of hydroxide ions.
