In the second set of experiments, the compound was compared to similar other compounds. Firstly, a test for CO3 was conducted. In the test, 0.1M Hcl was added to the solution and it was identified that the reaction did not fizz so there was no CO3 in the compound. Secondly, a test for Cl was conducted and in it the absence of halide ions was established. Finally, the test for KNO3 was conducted and it was identified that a brown ring was formed at the junction of FeSO4 and the H2SO4 mixed with the compound. Here we faced an issue because firstly the brown ring did not appear. Since all other tests were negative, and there was no white precipitate in the last test, negating the Cl ion, we redid the brown ring test. Same amount of reactance was used, and we compared the tube with rung to another with distilled water in order to find out the difference in darkness and we established KNO3 as the unknown compound. The cation is K by flame test and the anion is NO3 by the nitrate test was hence established.
