    For the unknown light source‚ it had almost every color‚ so it might have been be mercury because they have similar color beams and their color from the naked eye appeared as purple‚ which mercury‚ a light blue‚ is very close to in terms of it’s color on the spectrum. For the unknown flame crystals‚ it may NH4+ because the colors that appeared are very similar to the crystals. Next‚ chemicals have to be heated in the flame for the color to emit because heat adds energy to the substance making the

    spectrometry. We will do this by making 2‚ 4 a DNPH derivative and checking the melting points. Theory: By Using specific methods of compounds detection‚ we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identifications of the unknown ketone was accomplished using thin layer chromatography‚ melting point‚ and NMR spectrometry. Thin layer chromatography is very quick but sensitive way of determining the components
