Question

3. When the hydronium ion concentration of a solution is 1x10-4 M, What

pH of the solution? Is the solution acidic or basic?
the​

Answer 1

pH = 4

Solution is acidic

Step-by-step explanation:

Given data;

Hydronium ion concentration = 1 × 10⁻⁴ M

pH of solution = ?

Solution:

pH = -log [H₃O⁺]

pH = -log [ 1 × 10⁻⁴ ]

pH = 4

According to pH scale the pH 7 is neutral while the pH less than 7 is acidic and greater than 7 is basic. The given solution has pH 4 it means solution is acidic.
