What is the approximate size of solute particles in a solution?

A. 1 micrometer
B. 1 picometer
C. 1 millimeter D. 1 nanometer

The approximate size of solute particles in a solution is 1 nanometer.

Explanation:

Solute and solvent are the two components required to prepare a solution. Solute is the one which is dissolved in the solvent to prepare a solution. So solute should be of lesser concentration compared to the solvent. Also the particle size of solute should be lesser in size compared to the solvent for easy diffusion and substitution. Mostly it is seen that if the solute is finer and having a size of less than 1 nanometer can be easily dissolved in the solvent.

So for forming homogeneous solutions, the solute is considered to be of materials having the particle size of 1 nanometer for perfect dissolving.

Thus, the approximate size of solute particles in solution is 1 nanometer.
