Have you ever made chocolate milk with too much syrup? Some of the extra remains undissolved at the bottom of the glass. That’s because the milk has become a saturated solution, a solution containing the maximum concentration of one or more dissolved solutes in a solvent. In this case, the syrup would be the solute, and the milk the solvent. In a saturated solution, additional solutes won't dissolve (just like the extra chocolate syrup). Show Unsaturated solutions contain a smaller amount of solute than what can dissolve, leaving no remainder.
Supersaturated solutions contain more than the maximum amount of dissolved solute than the solution is able to dissolve at a given temperature.

Mass PercentMass percent expresses the concentration of a solution when both the mass of the solute and solution are given. To find mass percent, use the following formula: Mass % = msolute/msolution x 100% Where msolute = mass of solute msolution = mass solution Let’s try out a practice problem with a supersaturated solution example:
Knowns: msolute = 8.00g NaOH and msolution = 50.0g H2O Solving for mass percent Mass % = msolute/msolution x 100% Mass % = (8.00g)/(8.00g + 50.00g) x 100% Mass % = (8.00g)/(58.00g) x 100% Mass % = = 13.8% NaOH solution. FACTORS AFFECTING SATURATION
FAQs1. What is meant by supersaturated solutions? A solution that contains more solute than the solvent is capable of dissolving. It has more undissolved solute than the saturated solution that tends to crystallize and precipitate with the help of a seed crystal. 2. How do you know if a solution is supersaturated? If the solution is supersaturated, crystals will very quickly form around the solute you've added. 3. What are the examples of supersaturated solutions? The supersaturated solution contains more dissolved substances than a saturated solution. For example, 40g NaCl in 100ml H2O. The additional 4.0g NaCl remains undissolved. 4. What are the saturated and supersaturated solutions? The solution obtained by dissolving the maximum amount of solute at a given temperature is known as a saturated solution. A solution that contains more amount of solute than the required to saturate is known as a supersaturated solution.
