Question

11. A solution of K2Cr2O7 was prepared at room temperature by adding 78.7 g of solute to 300 mL of water. Is this solution saturated, supersaturated, or unsaturated? If supersaturated, what temperature would the solution need to be heated to for complete solubility to be achieved? If unsaturated, how much additional K2Cr2O7 can be added?
