Which of the following statements is true about suspension?

The correct answer is The particles of a suspension can be seen by the naked eye..

Key Points

• A suspension is a heterogeneous mixture in which solid particles do not dissolve in a liquid solution.
• The particles in a suspension are large enough to be seen with the naked eye.
• When left undisturbed, the particles in a suspension will eventually settle to the bottom due to gravity.
• The particles in a suspension can be separated from the liquid by filtration or decantation.

Additional Information

• Colloid:
  • A colloid is a mixture where very small particles of one substance are distributed evenly throughout another substance.
  • Unlike suspensions, colloids do not settle out upon standing, and the particles cannot be seen with the naked eye.
• Solution:
  • A solution is a homogeneous mixture of two or more substances.
  • The solute is the substance that is dissolved, and the solvent is the substance in which the solute is dissolved.
  • Solutions are transparent and do not scatter light.
• Emulsion:
  • An emulsion is a type of colloid formed by combining two liquids that normally don't mix.
  • Common examples include milk and mayonnaise.
• Decantation:
  • Decantation is a process for the separation of mixtures by removing a liquid layer that is free of precipitate.
  • This method is commonly used to separate suspensions.
