Based on the data provided, the pH of the H2SO4 solution is 1.62

What is pH of a solution?

The pH of a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution .

Mathematically, pH = - log [H+]

The pH is calculated from the molarity of the solution.

  • Molarity = number of moles/volume in Litres
  • moles = mass/molar mass

number of moles of H2SO4 = 3.25/98.08 = 0.0331 moles

Molarity of the H2SO4 solution = 0.0331/2.75 = 0.012 M

Since H2SO4 us a diprotic acid, [H+] = 2 × 0.012 = 0.024

Then;

pH = -log(0.024)

pH = 1.62

Therefore, the pH of the H2SO4 solution is 1.62
