Question: What is the effect of adding a strong acid to a solution of a weak base?

Options:

Correct Answer: Decrease in pH

Solution:

Adding a strong acid to a weak base will decrease the pH of the solution.

What is the effect of adding a strong acid to a solution of a weak base?

What is the effect of adding a strong acid to a solution of a weak base?

Step 1: Understand what a weak base is. A weak base is a substance that does not completely dissociate in water and has a higher pH (above 7).
Step 2: Understand what a strong acid is. A strong acid is a substance that completely dissociates in water and has a lower pH (below 7).
Step 3: When you add a strong acid to a solution of a weak base, the strong acid will release hydrogen ions (H+).
Step 4: The hydrogen ions from the strong acid will react with the weak base in the solution.
Step 5: This reaction will reduce the concentration of the weak base and increase the concentration of hydrogen ions in the solution.
Step 6: As a result, the overall pH of the solution will decrease, making it more acidic.
