Question

The pH of the ocean surface is about 8.1, although it does vary by location. What is the molar concentration of [H3O+] if the ocean has a pH of 8.15?

Answer 1

[H₃O⁺] = 7.08×10⁻⁹ M

Step-by-step explanation:

pH = - log [H₃O⁺]

[H₃O⁺] = 10^⁻pH

Therefore, [H₃O⁺] = 10⁻⁸¨¹⁵

[H₃O⁺] = 7.08×10⁻⁹ M
