The statement that is true about a buffer is that it reduces the amount of H+ in an acidic solution (option B).
<h3>What is a buffer solution?</h3>
Buffer is a solution that is used to stabilize the pH (excess acidity or alkalinity) of a liquid.
Buffers operate by neutralizing any added acid (H+ ions) or base (OH- ions) to maintain the moderate pH, making them a weaker acid or base.
Therefore, it can be said that the statement that is true about a buffer is that it reduces the amount of H+ in an acidic solution.
