The pH of a solution of 0.0025M H₂SO₄ is 2.3 means the solution is highly acidic.
How do we calculate pH?
pH of any solution will be calculated by using the below equation as:
pH = -log[H⁺]
Given that concentration of H₂SO₄ = 0.0025M
Let the volume of the acid is 1 liter means 0.0025 moles of H₂SO₄ are present.
- 1 moles of H₂SO₄ produces 2 moles of H⁺ ion
- So 0.0025 moles of H₂SO₄ produces 2(0.0025) = 0.0050 moles of H⁺ ion.
In 1 liter of solution 0.005 M of H⁺ ions are present. On putting this value in pH equation, we get
pH = -log(0.005)
pH = -(-2.3) = 2.3
Hence required pH of solution is 2.3.
