Which of the following when added to 20 mL of a 0.01 M solution of HCl would decrease its pH ?
- A 20 mL of 0.02 M HCl
- B 20 mL of 0.005 M HCl
- C 20 mL of 0.01 M HCl
- D 40 mL of 0.005 M HCl
Answer & Solution
Correct Answer
(A) 20 mL of 0.02 M HCl
Step-by-step Solution
Detailed explanation
For an acid, pH of an acid solution will be lower as the solution is more concentrated. \(\mathrm{pH}=-\log \left[\mathrm{H}^{+}\right]\)…
