Question: What is the effect of increasing the concentration of an acid on its pH?

Options:

Correct Answer: pH decreases

Solution:

Increasing the concentration of an acid decreases its pH, as pH is inversely related to the concentration of H+ ions.

What is the effect of increasing the concentration of an acid on its pH?

Step 1: Understand that acids release hydrogen ions (H+) when dissolved in water.
Step 2: Know that pH is a measure of how acidic or basic a solution is, with lower pH values indicating higher acidity.
Step 3: Realize that increasing the concentration of an acid means adding more H+ ions to the solution.
Step 4: Remember that as the concentration of H+ ions increases, the pH value decreases.
Step 5: Conclude that increasing the concentration of an acid will result in a lower pH.
