====================
NUMBER 3
(3a)
(i)The salt solution was acidic in nature, as it reacted with sodium trioxocarbonate(IV) (sodium carbonate) to produce effervescence and a white precipitate.
(ii)The salt solution contained a calcium or magnesium ion, as these ions form a white precipitate with sodium carbonate.
(iii)The reaction was exothermic, as the test tube became warm, indicating the release of heat energy.
(3b)
(i) PbSO4 (lead(II) sulfate) would not readily dissolve in water, as it is insoluble in water.
(ii) NaHCO3 (sodium hydrogen carbonate) produces effervescence with dilute mineral acids, as it reacts with acids to produce carbon dioxide gas.
(iii) NH4Cl (ammonium chloride) decomposes on heating, as it breaks down into ammonia and hydrogen chloride gases.
(iv) NaHCO3 (sodium hydrogen carbonate) dissolves in water to form an alkaline solution, as it is a basic salt.
(v) NH4Cl (ammonium chloride) sublimes on heating, as it changes directly from a solid to a gas without going through the liquid phase.
