Question

In some solutions, the concentration of $H_3{O}^{+}$ remains constant even when small amounts of strong acid or strong base are added to them. These solutions are known as:

• A. Colloidal solutions
• B. Buffer solutions
• C. True solutions
• D. Ideal solutions

Answer 1

The correct option is B Buffer solutions

In buffer solution there is a minimal change or no effect upon addition of strong acid or base.
So the concentration of $H_3{O}^{+}$ remains constant even when small amounts of strong acid or strong base are added to them. These solutions are known as buffer solutions.
