Test tube C did not mix well with the silver nitrate. The Iodine stayed at the bottom while the silver nitrate collected at the top. Test tube D did absolutely nothing‚ but get a little cloudy 5. Conclusion: The purpose of this lab was to see how silver nitrate affects the reactive Halogens and to see if it formed a precipitate. Most results were the same where a precipitate formed. Some took longer than others to form where as others had no effect to the silver nitrate. Two ways to improve the lab

When you mix copper‚ silver‚ and nitrate together‚ you will end up with silver nitrate solution will turn blue (it has become copper nitrate). On the piece of copper‚ there would be a coating of solid silver. If a chemical reaction is going to be observed when chemicals are mixed‚ heated or any other means of altering the substance‚ then we will be able to predict the products formed. If it is observed that in the original versus the changed substance no new substances are formed‚ the change is reversible

In this experiment‚ we have silver oxide and by using a bunsen burner‚ we will drive off all of the oxygen in the compound. We will do this by heating the silver oxide until the substance’s mass stays constant to know when all of the oxygen possible has been driven out. This process will occur through a series of heating and remassing. Silver oxide has many uses from batteries to military purposes. In a silver-zinc battery‚ silver oxide acts as the cathode and zinc as the anode. This battery is
