Question

Sand in water is an example of ______________ . (suspension/colloid).

Answer 1

• Suspensions are heterogeneous mixtures.
• A heterogeneous mixture is a mixture that is non-uniform and contains smaller parts.
• The particles in a suspension are larger than that of a solution and these particles can be separated by the filtration process.
• A suspension contains small, undissolved solid particles suspended in a fluid (a liquid or a gas ).
• These particles can be seen distinctly. So, when the mixture of water and sand is taken, the sand remains undissolved.
• Thus, sand in water is an example of a suspension.
