This phenomenon is known as recrystallization. The solubility of most solid solutes in a liquid solvent decreases as the temperature decreases. In this case, as the saturated solution of sucrose is cooled from 30°C to 4°C, the solubility of sucrose decreases.
As a result, the excess sucrose in the solution that cannot remain dissolved at 4°C begins to crystallize. The crystallized sucrose forms solid particles or crystals that can be observed in the container.
The approximate value of 28 represents the amount of sucrose that has crystallized out of the solution. It is an estimation based on the decrease in solubility of sucrose at lower temperatures. The exact amount of crystallized sucrose may vary depending on factors such as the initial concentration of the solution and the cooling rate, but an approximate value of 28 is expected.
A saturated solution of sucrose is prepared at 30°C. It is then placed in a refrigerator at 4°C. How much solid sucrose would you expect to find crystallised in the container?
The answer is approxmately 28 can you explain why
