Metals and acids experiment
Class practical
Many, but not all, metals react with acids. Hydrogen gas forms as the metals react with the acid to form salts. This is a well-tried standard class experiment often used in the introductory study of acids to establish that this behaviour is a characteristic property of acids.
Lesson organisation
The experiment is done first on a smaller scale using test-tubes (Lesson 1 below), with no attempt to recover the salts formed. This establishes that hydrogen production is a characteristic property of the reaction of metals and acids. It can then be done on a larger scale (Lesson 2 below), and the salts formed can be recovered by crystallisation, .
Lesson 1 is a series of test-tube experiments in which each working group establishes as a common feature that hydrogen is given off as metals react with an acid – if the metal reacts at all. This should take around 40 mins, and most classes should be able to do this version. Each working group needs a small selection of metals and acids to test.
The range of metals and acids tested can be extended to a teacher demonstration in the concluding part of this lesson.
