Question

The more acidic a solution, the ______ the pH.

Answer 1

The more acidic a solution, the lower the pH.

Explanation:

The more acidic a solution, the lower the pH because the pH scale is logarithmic and is inversely related to hydrogen ion concentration. Each single-unit drop in pH represents a tenfold increase in acidity and hydrogen-ion activity. Therefore, a highly concentrated, powerful acid will always register a value closer to zero on the scale.
