Question

Hydrogen gas adsorbed on surface of platinum is an example of solid in gas solution.

• A. True
• B. False

Answer 1

The correct option is A True

Platinum is present in solid state and when hydrogen gas is adsorbed on the surface of platinum then they are forming solid in gas solution because soild is very small and is present as solute and the amount of gas adsorbed is much more then platinum so it act as solvent and complete solution is known as solid in gas.
