WebbH2SO4 (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. install sdr# on raspberry pi
