pH of any acid can be calculated by using the following formula:
pH= -log(H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions.
Firstly we need to see the disociation of H2SO4 in water:
H2SO4(aq)————→ 2H+(aq) + (SO4)^2-(aq)
Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions.
Therefore, 0.01 moles of H2SO4 will give rise to 0.02 moles of H+ ions
Substituting the value of H+ in the formula,
pH=-log(0.02)
which is equal to 1.698.
Therefore pH of 0.01 moles of H2SO4 is 1.698 or 1.70.
