What is the pH of a solution with a concentration of 4.7 × 10-4 molar H3O+?
pH=-log(4.7E-4)
Use your calculator.
To determine the pH of a solution with a given concentration of H3O+, you can use the equation relating pH to the concentration of H3O+, which is pH = -log[H3O+]. In this case, the concentration of H3O+ is given as 4.7 × 10-4 M.
To calculate the pH, follow these steps:
1. Take the negative logarithm of the given concentration of H3O+:
-log(4.7 × 10-4) ≈ 3.33
2. The resulting value is the pH of the solution.
Therefore, the pH of a solution with a concentration of 4.7 × 10-4 M H3O+ is approximately 3.33.
