Question

which of the following do not give precipitate with AgNO3?

Explanation needed..☑️☑️

1) F-
2)I-
3)Cl-
4)Br-​

Answer 1

when AgNO3 reacts with the halides they form insoluble silver halides such as silver chloride , silver bromide and silver iodide.

Ag+(aq) + Cl-(aq) == AgCl (s) ppt

Ag+(aq) + Br-(aq) == AgBr (s) ppt

Ag+(aq) + I- (aq) == AgI (s) ppt

but silver fluoride is soluble, hence no ppt formed.

hope it helps!!
