When cinnabar,a ore of mercury, is heated in air, it is first oxidised and converted into mercuric oxide (HgO).
Mercuric oxide on further heating is then reduced to mercury .
The following are the equations which take place.
2HgS(s) + 3O2(g) -Heat → 2HgO(s) + 2SO2(g) ..2HgO(s) Heat → 2Hg(l) + O2(g).
Mercuric oxide on further heating is then reduced to mercury .
The following are the equations which take place.
2HgS(s) + 3O2(g) -Heat → 2HgO(s) + 2SO2(g) ..2HgO(s) Heat → 2Hg(l) + O2(g).
