Why is a mixture of sand and water not a true solution?
Answer and explanation
Correct answer: Sand does not dissolve uniformly in water
A true solution forms when the solute dissolves at the particle level and becomes uniformly distributed throughout the solvent. Sand is insoluble in water, so its grains remain separate, may be seen, and can settle on standing. Water is liquid and sand is solid; their states are not the reason that the mixture is not a solution.
