Reactions of Metals with Acid

This lesson highlights the ability of metals to displace hydrogen from a molecule or compound. The more reactive metals can release hydrogen from a molecule of water. The atoms within the water molecule are strongly bonded and only a metal that has a high reactivity will be able to displace the hydrogen. Other less reactive metals cannot do this, however this does not mean that they are completely unreactive. The next test is to see if the less reactive metals can displace hydrogen from an acid. Learners may need help observing the experiments and analysing the data collected. Again, writing and balancing chemical equations for each reaction is discussed and learners may need class time to complete this task.
