Answer 2

1. A saturated solution of picric acid which give yellow precipitate with alkaloid known as Mayer's reagent.

Mayer's reagent

• It is an alkaloidal reagent which precipitates and is also brought in use for detection of alkaloids in natural products. It's freshly prepared by dissolving mercuric chloride mixture with potassium iodide in water.
• Many alkaloids are precipitated by slightly acidic or neutral solution by Mayer's reagent. which gives a creamy colored precipitate.
• Mayer's reagent was invented by the German Chemist Julius Robert Von Mayer.
