Q: What is the pH of a 0.01 M HCl solution? (2021) 2021
Solution:
For a strong acid like HCl, pH = -log[H+] = -log(0.01) = 2.
Steps: 6
Show Steps
Step 1: Understand that HCl is a strong acid, which means it completely dissociates in water.
Step 2: Recognize that the concentration of HCl (0.01 M) is equal to the concentration of hydrogen ions [H+] in the solution.
Step 3: Write the formula for pH, which is pH = -log[H+].
Step 4: Substitute the concentration of hydrogen ions into the formula: pH = -log(0.01).
Step 5: Calculate the logarithm: log(0.01) = -2.
Step 6: Substitute this value back into the pH formula: pH = -(-2) = 2.
