Answer
pH = 6
Explanation
Given that:
The concentration of the acid [H⁺] = 10⁻⁷ M
What to find:
The pH of the strong acid solution.
Step-by-step solution:
The pH of the strong acid solution whose concentration is 10⁻⁷ M can be calculated using the pH formula.
The pH formula is given by: pH = -log[H⁺]
Substitute [H⁺] as 10⁻⁷ M, we have:
pH = - log(10⁻⁷)
pH = -(-6)
pH = 6
The pH of the strong acid solution whose concentration is 10⁻⁷ M is 6.
