Sulfuric acid, H2SO4, is neutralised when it is added to aqueous sodium hydroxide, NaOH. 2NaOH + H2SO4 → Na2SO4 + 2H2O. The reaction is exothermic. P is 1.25 mol / dm3 aqueous sodium hydroxide. Q is dilute sulfuric acid. Read all the instructions carefully before starting the experiments. Instructions You are going to do six experiments. (a) Experiment 1 • Rinse and fill a burette with Q. • Place the plastic cup into a beaker. • Use a volumetric pipette to add 25.0 cm3 of P to the plastic cup. • Use a measuring cylinder to add 20 cm3 of water to the plastic cup. • Stir the mixture in the cup w
