The reactivity series arranger metals in their increasing order of reactivity. The more reactive metals are easily oxidised compared to the less reactive metals, The order of reactivity is given as potassium > sodium > calcium > magnesium > aluminium > zinc > iron > tin > lead >hydrogen>copper > silver > gold > platinum. The more reactive metals can displace the less reactive metals.(a) Here, the given metals are Al, Fe, Ag, Na, Co, Au, Ca. The decreasing order of oxidation is, Na>Ca>Al>Fe>Co>Ag>Au (b) The half-reaction for the reduction of H+ is given as, 2H+ + 2e-→H2 (c) The metals which are less reactive than hydrogen can only be oxidized by hydrogen. Here the reactivity of Ag and Au is less than that of hydrogen, so they can be oxidized.
