Question 21

25.0 cm3 of sodium hydroxide solution with a concentration of 0.120 mol dm−30.120\,\mathrm{mol\,dm^{-3}}0.120moldm−3 reacts exactly with 30.0 cm3 of sulfuric acid. The equation is H2SO4+2NaOH→Na2SO4+2H2O\mathrm{H_2SO_4 + 2NaOH \rightarrow Na_2SO_4 + 2H_2O}H2​SO4​+2NaOH→Na2​SO4​+2H2​O.

Calculate the concentration, in mol dm−3\mathrm{mol\,dm^{-3}}moldm−3, of the sulfuric acid.
