Lassaigne's test (with silver nitrate) is commonly used to detect halogens such as chlorine, bromine and iodine but not useful to detect fluorine because the product `AgF` formed as

A

volatile

B

reactive

C

explosive

D

soluble in water

Text Solution

Verified by Experts

The correct Answer is:
D
AgF is highly soluble in `H_(2)O` therefore, NaF formed in the Lassaigne's extract does not produce a ppt. with `AgNO_(3)`.
