These questions cover what school trial papers ask about the properties of acids and bases again and again: indicators, the reactions of acids with metals, carbonates and bases, net ionic equations, acidic, basic and neutral salts, the history of acid-base models, gas volumes, and calorimetry for the enthalpy of neutralisation. Data sheet values used: J g⁻¹ K⁻¹ for water and dilute solutions (1 mL ≈ 1 g), and the molar volume of a gas at 25 °C and 100 kPa is 24.79 L mol⁻¹. They start easy and get harder. Stuck?
