Consider three unlabeled bottles, each containing small pieces of one of the following metals: magnesium, sodium, and silver. The following reagents are used for identifying the metals: pure water, a solution of 1.0M HCl, and a solution of concentrated HNO3
a) Which metal can easily be identified because it is much softer than the other two?Describe a chemical test that distingushes this metal from the other two, using only one of the reagents above.Write a balanced equation for the reaction that occurs.
b) One of the other two metals reacts readily with the HCl solution.Identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the HCl solution.
c) The one remaining metal reacts with the concentrated HNO3 solution.Write a balanced chemical equation for the reaction.
d) The solution obtained in part c) is diluted and a few drops of 1.0M HCl are added.What would be observed? Write a balanced chemical equation for the reaction
