Final answer:
Buffer capacity is related to the concentrations of a weak acid and its conjugate base in a buffer solution, and is not directly proportional to the temperature of the solution. A buffer with equal concentrations of weak acid and conjugate base has a higher capacity than one with unequal concentrations.
Step-by-step explanation:
The buffer capacity is the measure of a buffer solution's ability to resist pH changes when an acid or a base is added. It is not directly proportional to temperature but rather to the concentrations of weak acid and its conjugate base present in the buffer.
A higher concentration of these components leads to a greater buffer capacity, allowing the solution to maintain its pH with greater efficacy when faced with the addition of strong acids or bases. It is important to note that a buffer solution with equal concentrations of weak acid and its conjugate base will generally have a higher buffer capacity compared to a buffer with an unequal ratio of the two.
