Question: In a buffer solution, which of the following components is essential? (2023)

Options:

Correct Answer: Weak acid and its salt

Exam Year: 2023

Solution:

A buffer solution is made from a weak acid and its conjugate base (salt), which helps maintain pH.

In a buffer solution, which of the following components is essential? (2023)

Step 1: Understand what a buffer solution is. A buffer solution is a special type of solution that can resist changes in pH when small amounts of acid or base are added.
Step 2: Identify the components of a buffer solution. A buffer solution is typically made from two main components: a weak acid and its conjugate base (which is often a salt).
Step 3: Recognize the role of the weak acid. The weak acid helps to neutralize added bases, preventing the pH from rising too much.
Step 4: Recognize the role of the conjugate base. The conjugate base helps to neutralize added acids, preventing the pH from falling too much.
Step 5: Conclude that both the weak acid and its conjugate base are essential for a buffer solution to function properly.

Buffer Solution Components – A buffer solution is composed of a weak acid and its conjugate base, which work together to resist changes in pH.
