Question: What is the pH of a solution with [H+] = 1 x 10^-6 M?

Options:

Correct Answer: 6

Solution:

Using the formula pH = -log[H+], we find pH = -log(1 x 10^-6) = 6.

What is the pH of a solution with [H+] = 1 x 10^-6 M?

What is the pH of a solution with [H+] = 1 x 10^-6 M?

Step 1: Identify the concentration of hydrogen ions [H+]. In this case, [H+] = 1 x 10^-6 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^-6).
Step 4: Calculate the logarithm: log(1 x 10^-6) = -6.
Step 5: Substitute this value back into the pH formula: pH = -(-6).
Step 6: Simplify the expression: pH = 6.
