Ph of hydrogen gas
WebIt is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. Aqueous solutions that are 47.6% HBr by mass form a constant-boiling azeotrope mixture that boils at 124.3 °C. Webthat the Hydrogen Shot target by the U.S. Department of Energy 7 of producing clean hydrogen at a cost of $1.0/kg by 2030 is ambitious but not unrealistic. Because electricity prices will become the dominant component of the life-cycle cost of hydrogen by 2030, the attainment of the Hydrogen Shot target via electrolytic hydrogen ultimately
