Aluminum reacts with lead(II) nitrate. Aluminum metal (Al) coil was immersed into a test tube containing 0.25 M solution of lead(II) nitrate (Pb(NO3)2). Since aluminum is more reactive than lead, a single-displacement reaction occurred: Al + Pb(NO3)2 -> Pb + Al(NO3)3. The reaction proceeded very slowly since aluminum was protected by the aluminum oxide (Al2O3) layer. After a day, only small specs of lead were formed on aluminum coil.
