Q
Q: What is the pH of a solution where the concentration of H⁺ ions is 1.0 x 10⁻⁷ M?
Solution:
pH = -log[H⁺] = -log(1.0 x 10⁻⁷) = 7.
Steps: 5
Show Steps
Step 1: Identify the concentration of H⁺ ions in the solution, which is given as 1.0 x 10⁻⁷ M.
Step 2: Use the formula for pH, which is pH = -log[H⁺].
Step 3: Substitute the concentration of H⁺ ions into the formula: pH = -log(1.0 x 10⁻⁷).
Step 4: Calculate the logarithm: -log(1.0 x 10⁻⁷) equals 7.
Step 5: Conclude that the pH of the solution is 7.
