Solutions of hydrogen in palladium may be formed by exposing Pd metal to H2 gas. The concentration of hydrogen in the palladium depends on the pressure of H2 gas applied, but in a more complex fashion than can be described by Henry’s law. Under certain conditions, 0.85 g of hydrogen gas is dissolved in 214 g of palladium metal. (The density of the resulting solution is 11.7 g/cm3.)
