The solubility of a substance is 30 g per 100 mL of water at room temperature, 50 g per 100 mL of water at 80 ∘C. A student mixed 40 g of this substance with 100 mL of water at room temperature (stage 1), and then heated the mixture to 80 ∘C (stage 2). The mixture is then slowly cooled down to room temperature without any precipitation (stage 3). Finally, the student added a small crystal to the mixture and saw precipitation took place. This mixture is supersaturated at stage 2 heterogeneous at stage 1 homogeneous at stage 4 saturated at stage 3
