Question

consider the following solution. the purple dots represent the solute. select the image that best represents a concentrated version of this solution.

Explanation:

A concentrated solution has more solute per unit volume of solvent. In the first option, the volume of the solution is less (lower level in the beaker) but the number of solute particles (purple dots) is higher compared to the original. This means the solute - to - solvent ratio is increased, which is the characteristic of a concentrated solution. The second option has the same solute - to - solvent ratio as the original (same number of dots spread over similar volume). The third option has fewer solute particles in a smaller volume, which may not necessarily be more concentrated than the original (depending on the exact count, but relatively fewer). The fourth option also has fewer solute particles.

Answer:

The first option (the beaker with a lower volume of solution but a higher number of purple dots)
