A student is given a solid sample of ammonium copper(II) sulfate, (NH4)2Cu(SO4)2(\text{NH}_4)_2\text{Cu}(\text{SO}_4)_2(NH4)2Cu(SO4)2.
They are also provided with a dilute solution of sodium hydroxide, dilute hydrochloric acid, barium chloride solution, and standard laboratory equipment.
Describe the chemical tests the student should carry out to identify all three ions in the sample, including the observations they would expect to see and ionic equations for the reactions that occur.
