A chemist has a beaker of pure water held at 90 ^oC. He adds a small amount of sucrose (sugar) to the water, and all the sucrose dissolves, forming solution A.

The chemist continues to add sucrose to solution A, stirring regularly until the sucrose is dissolved. After a significant amount of sucrose is added and dissolves, additional sucrose will not dissolve. Any excess solid sucrose is filtered out, and the remaining solution is labeled Solution B.

Solution B is carefully cooled from 90 ^oC to 25 ^oC, giving solution C. No precipitation occurs during the cooling process.

A seed crystal is added to solution C, and sucrose precipitates.

Solution A is [ Select ] ["unsaturated", "saturated", "supersaturated"] .

Solution B is [ Select ] ["unsaturated", "saturated", "supersaturated"] , and the amount of sucrose in the water is equal to the [ Select ] ["heat capacity", "solute capacity", "solubility"] of sucrose in water at 90 ^oC.

Solution C is [ Select ] ["unsaturated", "saturated", "supersaturated"] .
