Sulfuric acid reacts with sodium hydroxide.

H2SO4+2NaOH→Na2SO4+2H2O \mathrm{H_{2}SO_{4} + 2NaOH \rightarrow Na_{2}SO_{4} + 2H_{2}O} H2​SO4​+2NaOH→Na2​SO4​+2H2​O

What volume of 0.200 mol/dm3\mathrm{mol/dm^{3}}mol/dm3 sulfuric acid exactly neutralises 30.0 cm3\mathrm{cm^{3}}cm3 of 0.100 mol/dm3\mathrm{mol/dm^{3}}mol/dm3 sodium hydroxide solution?
