Why hydrogen is not used as a reducing agent in metallurgy?give reactions.
Dear student,
Hydrogen is not used as a reducing agent in metallurgical processes because they will form hydrides when metal reacts with H2 at an elevated temperature. When hydrogen and oxygen present in the air combines , it will be explosive. The reducing power of H2 does not increase with temperature which is very important in metallurgy.
The reactions are given as follows;
H2 + FeO → Fe + H2O
H2 + PdCl2 → Pd + 2HCl
Regards
