4-nitrophenol characterization

Why would 4-nitrophenol form a white precipitate in a halogen test using silver nitrate and nitric acid if there is no halogen in its structure?

I don't think it should. Could you take a melting point of the precipitate to see if it is an Aryl halide. Or even a boiling point of the nitro compound to make sure it is what you think it is?

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3.

You might be knocking it out of solution; add a little ethanol and see if it dissolves/clarifies.

Are you sure it's not silver nitrite? Silver nitrite is used in nitrating aromatic rings in the Victor Meyer reaction.

perhaps it's insolubility at play?
