Which one of the following solutions is acidic?View Available Hint(s)Which one of the following solutions is acidic?A solution with [H3O+] = 2.5 x 10-8 MA solution with [OH-] = 1.0 x 10-7M

a) Not acidic

b) Not acidic

Explanation:

To determine if a solution is acidic, we need to calculate the pH. If the pH < 7, the solution is acidic.

a) A solution with [H₃O⁺] = 2.5 × 10⁻⁸ M

We will use the following expression.

pH = -log [H₃O⁺] = -log 2.5 × 10⁻⁸ = 7.6

Since the pH > 7, the solution is not acidic

b ) A solution with [OH⁻] = 1.0 × 10⁻⁷M

First, we will calculate the pOH.

pOH = -log [OH⁻] = -log 1.0 × 10⁻⁷ = 7.0

Then, we will calculate the pH.

pH = 14.0 - pOH = 14.0 - 7.0 = 7.0

Since the pH is 7, the solution is not acidic.

b.

the accuracy of the data.
