The pH of a solution can be calculated using the formula:
pH = -log[H3O+]
Given [H3O+] = 7.4 × 10^-9 M, we can substitute this value into the formula:
pH = -log(7.4 × 10^-9)
pH = -(-8.13)
pH = 8.13
Therefore, the pH of the cleaning solution with a [H3O+] = 7.4 × 10^-9 M is 8.13.
3. What is the pH of a cleaning solution with a [H3O+] = 7.4 × 10–9 M H3O+?
