Which method is best for separating sand from water?

Answer and explanation

Correct answer: B. filtration

  1. Step 1: Sand does not dissolve in water. Step 2. Pouring the mixture through filter paper holds back the sand and lets the water through. Answer: filtration. Why not the others: Chromatography separates dissolved dyes, a magnet only removes magnetic materials such as iron, and crystallisation recovers a dissolved solid from a solution.
