What is the reaction equation for HCL with the following metals?
Answer:
2 HCl + Pb --> PbCl2 + H2 (for Pb 2+)
4 HCl + Pb --> PbCl4 + 2 H2 (for Pb 4+)
2 HCl + Fe --> FeCl2 + H2 (for Fe 2+)
6 HCl + 2 Fe --> 2 FeCl3 + 3 H2 (for Fe 3+)
2 HCl + 2 Cu --> 2 CuCl + H2 (for Cu 1+)
2 HCl + Cu --> CuCl2 + H2 (for Cu 2+)
2 HCl + 2 Ag --> 2 AgCl + H2
2 HCl + Zn --> ZnCl2 + H2
6 HCl + 2 Al --> 2 AlCl3 + 3 H2
2 HCl + Mg --> MgCl2 + H2
Pb+2HCl =>PbCl2+H2
Fe+2HCl =>FeCl2+H2
Cu+2HCl=>CuCl2+H2
Zn+2HCl=>ZnCl2+H2
2Al+6HCl =>2AlCl3+3H2
Mg+2HCl =>MgCl2+H2
In single replacement reactions metals that have more than one oxidation number the lowest is used.Cu is the only exeption and the biggest is used(+2)
