Explanation:

(a) Biuret Test:

Add 2ml of sodium hydroxide and 5 to 6 drops of copper sulfate solution to it. Shake the test tube gently to mix the ingredients thoroughly and allow the mixture to stand for 4 – 5 minutes. If there is the appearance of bluish- violet color, it indicates the presence of protein.
