X, Y, and Z are three crystalline solids that are soluble in water and have common anion. To help you to identify X, Y and Z you are provided with the following experimental observations. Copy and complete the corresponding inferences in (a) to (e).
(a) A reddish-brown gas is obtained when X, Y, and Z are separately warmed with concentrated sulphuric acid and copper turning added to the mixture.
Inference 1: The common anion is _____ion.
(b) When X is heated, it melts and gives off only one gas which re-lights a glowing splint.
Inference2: The cation in X is either _____ or _____.
(c) The action of heat on Y produces a reddish-brown gas and yellow residue which fuses with a glass of the test tube.
Inference3: The metal ion present in Y is the____ ion.
(d) When Z is heated, it leaves no residue. Warming Z with sodium hydroxide solution liberates a gas that turns moist red litmus paper blue.
Inference4: Z contains the ____ cation.
(e) Write the equations for the following reactions:
