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? stage 1 demonstrated a saturated solution, stage 2 demonstrated an unsaturated solution, and stage 3 demonstrated a supersaturated solution. stage 1 demonstrated an unsaturated solution, stage 2 demonstrated a saturated solution, and stage 3 demonstrated a supersaturated solution. stage 1 demonstrated a supersaturated solution, stage 2 demonstrated a saturated solution, and stage 3 demonstrated an unsaturated solution. stage 1 demonstrated an unsaturated solution, stage 2 demonstrated a supersaturated solution, and stage 3 demonstrated a saturated solution.
