Reactions of metals with aqueous solutions of metal salts

Method

There are a number of solutions provided, along with a selection of metals. The object of this practical is to take a sample of a solution in a test tube and add a piece of metal to the solution.

Take a test tube rack and fill the correct number of test tubes with 5 cm3 of each metal salt solution.  Add a small piece of a metal to each tube, and note down all the observations you see, both before and after the metal is added, with special note being taken of the observations of the metal added to the solution.

Note down what solutions are available, what metals are available, and construct a table using a full page of A4 paper turned on its side, similar to the table below. Enter your observations as you make them into the table.

Questions

(i) Which of the metals is the most reactive? Explain your answer.

(ii) Which metal is the least reactive? Explain your answer.

(iii) Arrange the metals in order of their decreasing reactivity. Does this order agree with any reaction observations you have come across so far?

(iv) Write word and formulae equations for four different combinations of metal and metal salt solution that react together.
