I’m preparing a 1% solution of AgNO3 in ethanol.

This seems so fool proof. Get a gram of AgNO3 and dissolve it in enough ethanol to bring the solution to 100 mL.

I need this to last a few hours at least, but I keep getting a precipitate that forms after a while! Is there any way to avoid this?

Thanks.
