Step-by-step solution
2 stepsHere are the observations, identification of any evolved gases, and conclusions for each test, assuming C is a mixture of ammonium carbonate () and copper(II) sulfate ().
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.
Part (b)(i) - Adding in drops, then in excess.
- Observation: A blue
