3. Frequently Asked Questions (FAQ)
Why is lead acetate cotton plug used in the Limit test for Arsenic?
Lead acetate cotton plug is placed in the Gutzeit apparatus tube to trap and neutralize hydrogen sulphide (H2S) gas formed during the reaction, preventing it from blackening the mercuric chloride paper and giving false-positive results.
What are the best books for D.Pharm Pharmaceutical Chemistry?
Bentley and Driver's Textbook of Pharmaceutical Chemistry, Inorganic Pharmaceutical Chemistry by G.R. Chatwal, and Medicinal Chemistry by Ashutosh Kar are highly recommended reference resources.
