Why does mixing sand with water not form a true solution?
Answer and explanation
Correct answer: Because sand does not dissolve and spread uniformly in water
A true solution forms when solute particles dissolve and become uniformly distributed throughout the solvent at the particle level. Sand does not dissolve in water; its comparatively large particles remain separate and may settle at the bottom. Water can act as a solvent, but every solid is not soluble in it. Thus option A correctly explains why sand and water do not form a true solution.
