Question

We have to shake cough syrup before using because it is a ___________.

• A. solution
• B. colloid
• C. pure substance
• D. suspension

Answer 1

The correct option is D suspension

The undissolved particles can be observed by naked eyes. Cough syrup is a suspension because the drug particles are not soluble in the solvent and remain suspended throughout. The solute particles in the cough syrup settle down when it is kept undisturbed. Therefore, we shake the syrup before consuming it.
