Corrosion Iron and many other metals react with oxygen and moisture present in the atmosphere… 2. Explain the reactivity series of metals (potassium, sodium, calcium, magnesium, aluminium, (carbon), zinc, iron,(hydrogen), copper, silver, gold) in terms of the reactivity of the metals with water and dilute acids and that these reactions show the relative tendency of metal atoms to form cations. Metals like sodium and potassium are highly reactive. 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) + Heat. Alkali metals react with oxygen to form monoxides, peroxides, or superoxides. The reactivity of the metal determines which reactions the metal participates in. In each case, a solution of the metal hydroxide is produced together with hydrogen gas. You must know the test for hydrogen gas. Sodium and potassium react with cold water along with the production of a large amount of heat. Reaction of metals with water: Most of the metals react with water to form metal hydroxide and release hydrogen gas.
