Oxyhydrogen Gas

Oxyhydrogen Gas

 

a mixture of two parts hydrogen and one part oxygen. When ignited, oxyhydrogen gas explodes violently; it burns more slowly in the presence of porous platinum. The reaction 2H2 + 02 = 2H20 + 572.5 kilojoules (136.74 kcal) permits the attainment of high temperatures (about 2800° C). For this reason the flame of oxyhydrogen gas is used to melt quartz and platinum, as well as for gas welding and cutting metals.
