Question

The pH of a fruit juice is 5.6. Find the hydronium ion concentration, [H3O+], of the juice. Use the formula pH=-log[H3O+].

Answer 1

The hydroxonium ion concentration of the fruit juice whose pH as given in the task content is; 5.6 can be evaluated as; [H3O+] = 2.51 × 10^-6.

What is the hydroxonium ion concentration of the fruit juice whose pH is 5.6?

Since the given pH of the fruit juice is 5.6, the hydroxonium ion concentration of the fruit juice can be evaluated by means of the formula as follows;

pH=-log[H3O+].

5.6 = -log[H3O+].

-5.6 = log[H3O+].

[H3O+] = antilogarithm (-5.6)

[H3O+] = 2.51 × 10^-6.
