Question

Choose the correct example for a true solution.

• A. Blood
• B. Milk
• C. Salt solution
• D. Sand and water

Answer 1

The correct option is C

Salt solution

A true solution is a homogeneous mixture. The solute and solvent molecules cannot distinguish even under a microscope. The composition and properties of a true solution are the same throughout. A true solution is clear and transparent. The components of a true solution (the solute and the solvent), cannot be separated by filtration because both solute particles and the solvent molecules are very small as compared to the pores in the filter paper. Similarly, we cant separate salt and water from the mixture by filtration whereas the rest of the options can be separated easily
