What is the chemical equation for aqueous sodium chloride and aqueous silver nitrate react to form solid silver chloride and aqueous sodium nitrate?
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.)
