For this buffered solution with a pH of 7.5, B. The pH would become less than 7.0.
<h3>What is pH?</h3>
In Science, pH literally means the power of hydrogen ions and it can be defined as a measure of the molar concentration of hydrogen ions in a particular solution. Thus, it is typically used to specify the acidity, neutrality or basicity of any chemical solution.
On a pH scale, a solution with a pH of 7 is <u>neutral</u> while a solution with a pH below 7 is acidic and it's basic (alkaline) when its pH is above 7.
In this scenario, a buffered solution with a pH of 7.5 would become less than 7.0 when a small amount of acid is added to it.
