Question

If a sample of a certain solution is determined to have a
`|H_3O^+|` concentration of
`8.94 x 10^-4` moles/liter, what is its pH? Round off your answer to one decimal place.

Answer 1

9514 1404 393

Answer:

3.0

Explanation:

The pH is computed from ...

pH = -log(hydrogen ion concentration)

pH = -log(8.94×10^-4) ≈ 3.049 ≈ 3.0

The pH of the solution is about 3.0.
