Which combination of compounds will create a buffer solution? a weak acid and a weak base a weak acid and its conjugate base a strong acid and its conjugate base a strong acid and a strong base

The correct answer is a solution of a weak acid and its conjugate base.

Explanation:

An aqueous solution comprising a weak acid and its conjugate base or a weak base and its conjugate acid is known as a buffer. The pH of a buffer fluctuates very little when a small amount of strong base or acid is supplemented to it. It has a function in preventing any change in the pH of a solution, in spite of the solute.  

The buffer solutions are used as a means of maintaining the pH at almost the same value in a wide array of chemical uses. For example, human blood is a buffer solution.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
