What is hydrogen and its compounds?
Hydrogen is a lighter-than-air, flammable, diatomic gas. It is colorless and only sparingly soluble in solvents. It boils at -253.5 deg C. Platinum metal or heat can catalyze the reaction of hydrogen with oxygen to form water. In hydrogen fuel cells, the chemical oxidation of hydrogen to water produces electricity.
