Place 0.5 grams of sodium chloride into one of the bottles, and the 1 gram of silver nitrate into the other.
Pour one tablespoon of ionized water into each of the bottles.
Put the cap on each bottle tightly and shake well. If the material inside doesn't complete dissolve, add a little more water and shake again.
Add the salt solution to the silver nitrate solution. It will immediately begin to react.
Place the cap on the solution and shake well. Let it stand for five minutes.
Unscrew the cap and pour the excess water out. The remaining white powder is silver chloride. It's heavier than the water and should stay on the bottom of the glass as the water is poured. However, as a precaution, use a cheesecloth or a very fine strainer.
