Study Notes

Sugar Crystallization

Sugar crystals are formed through a process involving evaporation and supersaturation.
A thread is hung in a sugar solution, and as evaporation occurs, the solution becomes supersaturated.
Sugar starts to adhere to the thread, leading to the formation of sugar crystals.
This method of obtaining sugar crystals is known as crystallization.

Common Salt from Sea Water

Common salt (sodium chloride) can be extracted from seawater.
A flask is filled with seawater and sealed with a cork, ensuring no evaporation loss.
Heating the flask causes the water to vaporize, leaving impurities behind.
The vapor travels through a delivery tube and is then condensed back into liquid form.
The resulting product is distilled water, while salt remains in the flask after evaporation.
