Here are the observations and inferences for each test: |l|l|l| Test & Observation & Inference \\ 1. Put 1 spatular of the Sample in a watch glass, add few drops of concentrated H_2SO_4. Warm gently for a while. & Black residue forms. & Presence of carbohydrates. \\ 2. Add a few drops of distilled water to the solid Sample and boil. & Sample dissolves (or partially dissolves) to form a solution. & Sample is soluble in hot water. \\ 3. To 2 cm^3 of Solution of Sample in a test tube, add few drops of Iodine Solution. & Blue-black coloration. & Presence of starch. \\ 4. Fehling's test (Benedict's test) - To 2 cm^3 of Solution of Sample in test tube, add 2 cm^3 of Fehling's Solution and heat for a while. & Brick-red precipitate forms. & Presence of reducing sugars. \\ 3|c|TEST FOR PROTEINS AND AMINO ACIDS \\ 5. Biuret Test - To 2 cm^3 of solution of Sample in a test tube, add a few drops of dilute NaOH followed by few drops of CuSO_4 solution. & Violet/purple coloration. & Presence of proteins (peptide bonds). \\ 6. Millon's Test - Add few drops of Millon's reagent to the solution of the sample and warm the mixture. & Red precipitate forms. & Presence of proteins containing tyrosine. \\ Send me the next one 📸
