The electrochemical investigation of reactions on the lead electrode in 1 M aqueous hydrochloric acid was carried out by means of cyclic voltammetry, rotating disk electrode techniques, potentiostatic current-time transients. Attenuation was focussed on processes occurring at the electrode/solution interface...
Lead dichloride is precipitated by adding hydrochloric acid or any chloride salt solution to a cold solution of lead nitrate or other lead(II) salt: Pb2+ + 2Clˉ → PbCl2 Alternatively, it is prepared by treating lead monoxide or basic lead carbonate with hydrochloric acid and allowing the ...
Lead does not evolve hydrogen readily with acids. Nitric acid attacks the metal readily, forming lead nitrate and oxides of nitrogen: 3Pb + 8HNO3 → 3Pb(NO3)2 + 2NO + 4H2O This reaction is faster in dilute nitric acid than strong acid. Hydrochloric acid has little effect on the metal...
The compound PbH4, combining lead and hydrogen, is obtained in small quantities upon the action of dilute hydrochloric acid on Mg2Pb. PbH4, a colorless gas, readily decomposes to yield Pb and H2. Lead combines with halogens upon heating to form the halides PbX2 (X is a halogen), which...
