Question: What is the pH of a solution that is 0.01 M in both HCl and NaOH?

Options:

Correct Answer: 7

Solution:

HCl and NaOH neutralize each other, resulting in a neutral solution with pH = 7.

What is the pH of a solution that is 0.01 M in both HCl and NaOH?

What is the pH of a solution that is 0.01 M in both HCl and NaOH?

Step 1: Identify the substances in the solution. We have HCl (a strong acid) and NaOH (a strong base).
Step 2: Determine the concentration of each substance. Both HCl and NaOH are at 0.01 M.
Step 3: Understand that HCl will release H+ ions and NaOH will release OH- ions when dissolved in water.
Step 4: Since HCl and NaOH are both present in equal concentrations (0.01 M), they will neutralize each other.
Step 5: When HCl and NaOH neutralize, they form water (H2O) and salt (NaCl), resulting in a neutral solution.
Step 6: A neutral solution has a pH of 7.
