Question

What is the ph of a solution of h2so4 that has [h3o ] = 5.45 × 10–5 m?

Answer 1

The pH of a solution of sulphuric acid that has hydronium ion concentration is 4.26.

How do we calculate pH?

pH of any solution is define as the negative logarithm of the concentration of H⁺ ion present in any solution, i.e.

pH = -log[H⁺]

In the question, it is given that:

Concentration of hydronium ion or H⁺ ion = 5.45×10⁻⁵ M

So, pH will be:
pH = -log(5.45×10⁻⁵)

pH = -(-4.26)

pH = 4.26

Hence required pH is 4.26.
