A student labels two 250 milliliter beakers with the letters A and B. She puts 100 milliliters of water in each of them. She adds some salt to beaker A and stirs until the salt dissolves completely. Then she adds another 50 milliliters of water to beaker A. She adds more salt to beaker B, and the salt in beaker B doesn't completely dissolve in the water even after much stirring.

Answer is: solution B is saturated and solution A is unsaturated.

Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is added to saturated solution, that solute will not dissolve.

Unsaturated solution means that more of a substance can be dissolved (in this example salt).
