This reaction is commonly used to illustrate basic solubility rules, and solubility equilibria.
All nitrates are soluble, hence silver nitrate is soluble; and all halides are soluble, EXCEPT for
Thus silver nitrate is soluble, but silver chloride precipitates from solution as a curdy white solid.
We write the net ionic equation as:
Silver chloride is a curdy white solid; silver bromide is a creamy yellow; and silver iodide is bright yellow. (On standing the silver halides tend to reduce to silver metal, and the precipitates darken.)
