Asolution is a homogeneous mixture of one or more solutes dissolved in a solvent. a specific volume of solvent is only able to dissolve a limited amount of solute. as long as the solvent is able to dissolve more solute, the solution remains unsaturated. when the solvent can no longer dissolve additional solute, the solution is saturated. at this point, any additional solute will fall to the bottom of the container. the amount of solute that can be dissolved in a given amount of solvent at a specific temperature and pressure is defined as the solubility of the solute. consider the solubility curves of several salts in water. based on the information here, if 220 grams of the salt kbr are added to 100 ml of water at 100oc, we would label that solution as a) insoluble b) saturated c) supersaturated d) unsaturated

In stage 1 of his lab, gunther adds 20 mg of solute into a solution. he stirs it and it completely dissolves. in stage 2, he adds 20 mg more of solute and stirs, but this time, some settles out. in stage 3, he then heats his solution, adds 20 mg more,and the solute completely dissolves. which best explains his experiment? a)stage 1 demonstrated a saturated solution, stage 2 demonstrated an unsaturated solution, and stage 3 demonstrated a supersaturated solution. b)stage 1 demonstrated an unsaturated solution, stage 2 demonstrated a saturated solution, and stage 3 demonstrated a supersaturated solution. c)stage 1 demonstrated a supersaturated solution, stage 2 demonstrated a saturated solution, and stage 3 demonstrated an unsaturated solution. d)stage 1 demonstrated an unsaturated solution, stage 2 demonstrated a supersaturated solution, and stage 3 demonstrated a saturated solution.
