why does salicylic acid give a positive test with FeCl3
Salicylic acid is considered to be a phenolic (aromatic) acid. The -OH group in salicylic acid gives a few tests of alcohols also like esterification, reaction with Na, etc.
what would be seen if you analyzed salicylic acid in FeCl3?
HOC6H4COOH + NaOH = HOC6H4COONa + H2O
Bismuth Subsalicylate reacts with Hydrochloric acid to form Bismuth Oxychloride and Salicyclic acid C7H5BiO4 + HCL -------> BiOCl + C7H6O3
Formic acid gives positive result in both tollen's test and fehlings test. but acetic acid doesnot.

not if it is a pure form of aspirin if itt test positive (turns purple) it is impure and still has salicyclic acid
salicyclic acid lauric acid palmitic acid oleic acid stearic acid
what would be seen if you analyzed salicylic acid in FeCl3?
O-hydroxy benzoic acid or 2-hydroxy benzoic acid.
Because aspirin does not contain OH group like salicyclic acid so ferric chloride preferes to react with a compounds that have OH group.
HOC6H4COOH + NaOH = HOC6H4COONa + H2O
Yes they do so.
Hcl cl- is a strong nucleophile capible of substituting the oH group of the salicyclic acid,, my best guess
Bismuth Subsalicylate reacts with Hydrochloric acid to form Bismuth Oxychloride and Salicyclic acid C7H5BiO4 + HCL -------> BiOCl + C7H6O3

yes... it gives silver particle deposition at the bottom of test tube
