How to Calculate pH of a Solution at 25°C?

What is the method to calculate the pH of a solution at 25°C?

If you have a solution with a [H₃O+] concentration of 9.5×10⁻⁹M, how can you determine the pH?

Calculation of pH in a Solution at 25°C

The pH of a solution with a certain concentration of H₃O⁺ ions can be determined by taking the negative logarithm of the H₃O⁺ ion concentration.

In the case of a solution with [H₃O+]=9.5×10⁻⁹M at 25°C, you can calculate the pH using the following steps:

First, determine the log of the H₃O+ concentration: log(9.5×10⁻⁹) ≈ -8.02

Next, take the negative of the result: -(-8.02) = 8.02

Therefore, the pH of the solution with a concentration of 9.5×10⁻⁹M H₃O⁺ ions at 25°C is approximately 8.02.

By applying this method, you can easily calculate the pH of a solution based on the concentration of H₃O⁺ ions present.
