Okay, let let's fill in the table based on the observations and standard chemical tests. a) i) Test Procedure: To 2 cm³ of solution X is added 5 drops of NaOH(aq) and warmed. Observation: A colourless pungent gas is evolved that turns damp red litmus paper blue. Conclusion: The gas is ammonia (NH_3), indicating the presence of ammonium ions (NH_4^+(aq)). ii) Test Procedure: A sample of X is strongly heated in a test tube. Observation: A brown gas is evolved. Conclusion: A brown gas (nitrogen dioxide, NO_2)
