In a buffer solution, which component resists changes in pH? (2020)
Strong acid
Weak acid and its salt
Strong base
Water
A buffer solution typically consists of a weak acid and its conjugate base (salt), which helps to resist changes in pH when small amounts of acid or base are added.

Q: In a buffer solution, which component resists changes in pH? (2020)
Solution: A buffer solution typically consists of a weak acid and its conjugate base (salt), which helps to resist changes in pH when small amounts of acid or base are added.
Steps: 5
Step 1: Understand what a buffer solution is. A buffer solution is a special type of solution that can maintain a stable pH level.
Step 2: Learn about the components of a buffer solution. It usually contains a weak acid and its conjugate base (which is often a salt).
Step 3: Know the role of the weak acid. The weak acid can donate protons (H+) when a base is added, helping to prevent an increase in pH.
Step 4: Understand the role of the conjugate base. The conjugate base can accept protons (H+) when an acid is added, helping to prevent a decrease in pH.
Step 5: Conclude that both the weak acid and its conjugate base work together to resist changes in pH when small amounts of acid or base are added.
