Here are the observations, identification of any evolved gases, and conclusions for each test, assuming C is a mixture of ammonium carbonate ( (NH_4)_2CO_3) and copper(II) sulfate (CuSO_4). Step 1: Part (a) - Dissolving C and testing with litmus. Observation: The mixture dissolves in distilled water to form a blue solution. Red litmus paper turns blue. Gas(es) evolved: None. Conclusion: The solution is alkaline*. Step 2: Part (b)(i) - Adding NaOH_(aq) in drops, then in excess. Observation: A blue
