What type of solution is the H ₂ in palladium?

Options

  1. AGas as solute and solid as solvent
  2. BGas as solute and liquid as solvent
  3. CGas as solvent and solid as solute
  4. DLiquid as solute and gas as solvent

Correct answer

A. Gas as solute and solid as solvent

Step-by-step solution

H ₂ in palladium describes a solid solution with gas dissolved in a solid matrix. Since hydrogen ( H ₂ ) is a gas and palladium (Pd) is a solid, the solution contains gas as solute and solid as solvent. This configuration corresponds to option A .
