Question: What is the pH of a solution with a hydrogen ion concentration of 0.001 M? (2022)

Options:

Correct Answer: 3

Solution:

pH = -log[H+]. pH = -log(0.001) = 3.

What is the pH of a solution with a hydrogen ion concentration of 0.001 M? (2022)

What is the pH of a solution with a hydrogen ion concentration of 0.001 M? (2022)

Step 1: Identify the hydrogen ion concentration given in the problem, which is 0.001 M.
Step 2: Recall the formula for calculating pH, which is pH = -log[H+].
Step 3: Substitute the hydrogen ion concentration into the formula: pH = -log(0.001).
Step 4: Calculate the logarithm: log(0.001) is equal to -3.
Step 5: Apply the negative sign: pH = -(-3) = 3.
