Question

What's the pH of a solution with a concentration of hydronium ions of 5.29×10–10?Question 4 options:A) 3.34B) 5.29C) 9.28D) 12.1

Answer 1

Answer:

The answer is C.

Step-by-step explanation:

We are given: H3O+ = 5.29 * 10 ^ -10

We use the pH formula to find pH:

pH = -log[H3O+]

= -log[5.29 * 10 ^ - 10]

= 9.28
