Which option is an incorrect statement?
Answer and explanation
Correct answer: Soda water is a gas-in-solid solution
In soda water, carbon dioxide is the gaseous solute, but water is the liquid solvent. Therefore soda water is a gas-in-liquid solution, not a gas-in-solid solution. Air is gas in gas, salt water is solid in liquid, and brass is solid in solid. The error in option D is the claim that the solvent is solid; it is actually liquid water.
