Which option corrects a wrong idea about solutions?
Answer and explanation
Correct answer: Solutions may exist in solid, liquid, or gaseous state
A solution is a homogeneous mixture, and its physical state depends on the states of its components. Solutions can therefore be solid, liquid, or gaseous: brass is a solid solution, salt water is liquid, and air is gaseous. Water is not the only possible solvent, and the solute may be a gas or liquid as well as a solid. Thus A corrects the misconception.
