Question

10.30 Indicate whether each of the following solutions is acidic,

Answer 1

Answer:

Basic

Explanation:

The pH scale is measured from 0 to 14.

At the pH scale of 7, a solution is neutral.

Any solution above 7 is basic.

Any solution below 7 is acidic.

Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:

pH = -log[H₃O⁺]

pH = -log(6.0 x 10⁻¹²)

pH = 11.22

As you can see, the solution must be basic because the pH lies within the basic range.
