Reaction with water

Lead virtually has no reaction with cold water or steam.

Reaction with oxygen

On strong heating, lead melts to a silvery ball. A powder is gradually formed which is orange when hot and yellow when cold.

lead + oxygen > lead (II) oxide
2Pb(s) + O2(g) > 2PbO(s)

Reaction with dilute acids

Lead reacts very slowly with dilute hydrochloric acid to give lead chloride and hydrogen gas.

lead + hydrochloric acid > lead chloride + hydrogen
Pb(s) + 2HCl(aq) > PbCl2(aq) + H2(g)

Lead reacts very slowly with dilute sulphuric acid to give lead sulphate and hydrogen gas.

lead + sulphuric acid > lead sulphate + hydrogen
Pb(s) + H2SO4 (aq) > PbSO4(aq) + H2(g)

Lead reacts very slowly with dilute nitric acid to give lead nitrate and hydrogen gas.

lead + nitric acid > lead nitrate + hydrogen
Fe(s) + 2HNO3(aq) > Fe(NO3)2(aq) + H2(g)

Generally, reactions of cold, dilute acids with lead are very slow. [image]
