Question

What happens to the pH of the solution when an acidic solution is titrated with drops of base?

• A. Increase
• B. Decrease
• C. Remain the same
• D. Approach zero
• E. None of the above

Answer 1

Answer: (A)

Increase

When an acidic solution is titrated with drops of base, the pH of the solution increases. More acidic solution has lower pH than less acidic (or basic) solution. When an acidic solution is titrated with base, its acid strength decreases and hydrogen ion concentration decreases. This increases pH of solution.
Note: $pH=-log\left[H^{+}\right]$
