Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are

Copper-Silver Nitrate Reaction Introduction In this experiment copper wire will be placed in a solution of silver nitrate. This single replacement reaction will produce a blue solution of copper II nitrate and solid silver. By weighing the reactants before the reaction‚ the mass of silver produced can be predicted. This theoretical yield can be compared to the actual yield of silver. Purpose Students will compare the theoretical mass of silver with the actual mass of silver from the single

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
