Question

ASAP HELP !!!!!!!!!!!!!!What is the pH of a solution with a hydronium ion concentration of 5.6 × 10-7?

(pH = -log[H3O+])

A.
5.6

B.
6.25

C.
7.00

D.
14.40

Answer 1

it is indeed B 5.25

Explanation:

Answer 2

B: 6.25

Explanation:

The pH is calculated with the formula pH = - log [H3O+], where [H3O+] is the concentration of H3O+

=> [H3O+] = 5.6 * 10^ -7.

=> pH = - log (5.6 * 10 ^-7) = 6.25

That is a slightly acid pH, because pH is in the range 0 to 14, and 7 is neutral.
