John was complaining of stomach pains after drinking some tea. After diagnosis by the medical doctor, it was noted that the tea might have been contaminated with sample L. Perform the experiment to identify the cation and anion present in the tea sample based on the following tests and answer the questions that follow: (i) Appearance of sample L (ii) Action of heat on sample L in a test tube (iii) Action of dilute sulphuric or hydrochloric acid to solid sample (iv) Action of concentrated sulphuric acid on solid sample (v) Flame test (vi) Solubility of the sample (vii) Confirmatory test for the anion (viii) Confirmatory test for the cation. Questions (a) Prepare a relevant Table showing the qualitative analysis results. (b) Identify the ions in sample L. (c) What is the name of sample L? (d) Write the reaction equation to indicate what took place in test (viii). (e) Write the reaction equation to indicate what took place in test (iv)
