WebTest Tube Reactions. Simple test tube reactions can be done to identify the following ions: Group 2 ions (M 2+) Ammonium ions (NH 4+) Halide ions (X -) Hydroxide ions (OH -) Carbonate ions (CO 32-) Sulfate ions (SO 42-) If the sample to be tested is a solid, then it must be dissolved in deionised water and made into an aqueous solution. WebRequired Practical 2 – Measurement of an enthalpy change • Hess’s Law can be used to find an enthalpy change that cannot be measured directly: ΔH 3 = ΔH 1 - ΔH 2 Measuring ΔH 1 and ΔH 2 directly: 1) Weigh 3.90 – 4.10 of anhydrous copper sulphate in a dry stoppered weighing bottle.
