Experiment 5: Ionic Reactions in Aqueous Solutions a) lonic compounds containing chromate (CrO42-) ions are insoluble except when the cations are in group 1A or ammonium (NH4+). b) In general acid turns blue litmus paper from blue to red. c) When base reacts with acid, gas is evolved. d) When HCl(aq) is poured on the CaCO3(s) the solution gets cooler. e) If you want to test a substance is a base, a red litmus paper would give the best result.
