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]
