15. What is true about concentration of a solution? *
Naya [18.7K]
<h3>Answer:</h3>

A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.

<h3>Explanation:</h3>
  • A solution is made by dissolving a solute in a solvent.
  • For example dissolving a salt in a solvent such as water results to a solution.
  • Solution may either be saturated or unsaturated.
  • Unsaturated solution is a solution that can dissolve more solute upon addition because it has not reached saturation.
  • A saturated solution on the other hand is a solution that has maximum solute and the concentration of solute is maximum and thus the solvent can not dissolve any more solute.
  • Therefore, a saturated solutions contain maximum concentration of a solute dissolved in the solute.
