The formation of a white precipitate which turns brick-red on heating indicates the presence of proteins.
It is C, Reddish brown
Brick red is the final colour for Benedict's test not Million's test.
Benedict's test is for detecting reducing sugars like glucose
Million's test = reddish brown
Benedict's test = brick red
When Millon's reagent is added to egg white (albumen) in a test tube, the solution turns:
Red or reddish-brown
This is due to the presence of tyrosine, an amino acid in the egg white protein.
the answer is reddish brown @mySchool a reddish brown color is usually observed in millions test after heating
The correct answer is: C. reddish brown
Explanation:
Millon’s reagent is used to test for phenolic compounds, especially the amino acid tyrosine, which is present in egg-white (albumin).
When Millon's reagent is added to egg-white and heated, it forms a white precipitate initially, which then turns reddish brown upon further heating.
This confirms the presence of tyrosine in proteins.
So, the color change you're looking for is:
White precipitate → Reddish brown
When a few drops of Millon's reagent are added to an egg-white solution (which contains proteins, particularly albumin), a white precipitate forms initially. Upon heating, this white precipitate changes to a BRICK-RED OR REDDISH-BROWN color.
