Question: What is the pH of a solution with [H+] = 1 x 10^-7 M? (2023)

Options:

Correct Answer: 7

Solution:

pH = -log[H+] = -log(1 x 10^-7) = 7.

What is the pH of a solution with [H+] = 1 x 10^-7 M? (2023)

What is the pH of a solution with [H+] = 1 x 10^-7 M? (2023)

Step 1: Identify the concentration of hydrogen ions [H+]. In this case, [H+] = 1 x 10^-7 M.
Step 2: Use the formula for pH, which is pH = -log[H+].
Step 3: Substitute the value of [H+] into the formula: pH = -log(1 x 10^-7).
Step 4: Calculate the logarithm: -log(1 x 10^-7) equals 7.
Step 5: Therefore, the pH of the solution is 7.
