What is the safest method to solve questions on types of solutions?
Answer and explanation
Correct answer: First identify solute and solvent, then match their states
The governing method is classification by the solute, solvent, and their physical states. First identify which substance dissolves and which substance is the medium. Then determine whether each is a gas, liquid, or solid and express the type in solute-in-solvent order, such as gas in liquid. This works for aqueous, non-aqueous, gaseous, solid, and alloy solutions. Colour or memory alone cannot reliably determine the type, so A is correct.
