Question

The concentration of H3O+ in the buffer prepared in the previous question is 1.80×10−5 . What is the pH of the solution?

Answer 1

pH = 4.7

Step-by-step explanation:

Given data:

Concentration of H₃O⁺ = 1.80×10⁻⁵ M

pH of solution = ?

Solution:

Formula:

pH = -log[H₃O⁺]

pH = -log[1.80×10⁻⁵]

pH = 4.7

pH of solution is 4.7.
