Calculate the pH if the [H^+] = 9.71 ×<br> 10^-8
oksano4ka [1.4K]

Answer:

pH = 7.01

Explanation:

The pH can be calculated using the formula:

pH = -log[H⁺]

In this formula, [H⁺] represents the concentration of H⁺. Since you have been given this value, you can easily find the pH.

pH = -log[H⁺]

pH = -log[9.71 x 10⁻⁸]

pH = 7.01
