does hydrogen react with acid? | Yahoo Answers

3/1/2008· 3 Answers. Acids do not normally react with hydrogen, because the acid forms by a precursor compount bonding to hydrogen in the first place; it doesn''t tend to react further with hydrogen. You don''t need to capitalize the H in hydrogen, since it is a common noun. However, the chemical syol, H, is always capitalized.

Calcium hydride - Wikipedia

Reduction of metal oxides CaH 2 is a reducing agent for the production of metal from the metal oxides of Ti, V, Nb, Ta, and U. It is proposed to operate via its decomposition to Ca metal: TiO 2 + 2 CaH 2 → Ti + 2 CaO + 2 H 2 Hydrogen source CaH 2
