Chemistry - Liquid Solution Question with Solution | TestHub

Hydrogen (${\mathrm{H}}_2$) is a gas and palladium is a solid metal.

In the mixture of ${\mathrm{H}}_2$ in palladium, hydrogen is present in a smaller proportion and acts as the solute, while palladium is present in a larger proportion and acts as the solvent.

Therefore, it is a solid solution of a gas as the solute and a solid as the solvent.

Answer: Gas as solute and solid as solvent
