A buffer will
A) enhance changes in the pH of the solutions.
B) resist drastic changes in the pH of the solutions.
C) have no effect on the pH of the solutions.
D) make a solution more acidic.
E) make a solution more basic.
Buffer
A chemical substance that helps maintain a stable pH in a solution by neutralizing small amounts of added acid or base.
pH
A scale used to specify the acidity or basicity of an aqueous solution, with low values indicating acidity and high values, basicity.
Solutions
Homogeneous mixtures composed of two or more substances where one substance, the solute, is dissolved in another, the solvent.

Final Answer :
B
Explanation :
Buffers are designed to resist drastic changes in pH when small amounts of acid or base are added to a solution. This is because they consist of a weak acid and its conjugate base (or a weak base and its conjugate acid), which can neutralize small amounts of added acid or base, thereby maintaining the pH at a nearly constant value.
