Sugar can be separated from a sugar and water solution through the process of crystallization. Crystallization is obtained by first turning the solution into a "supersaturated solution" through heating, and then cooling that supersaturated solution so that crystal formation can begin.Know More
When sugar, or any other substance that's soluble in water, is added to water, the substance breaks into incredibly small particles which are not visible to the naked eye. Water dissolves the solid substance, in this case sugar, and continues to do so until the solution becomes saturated.
Saturation of a solution is indicated by the point at which the solvent can't dissolve any more of the solute. After a solution has reached saturation, it can be turned into a supersaturated solution by heating up the solution and adding more solute to the solution. Heating up a solution facilitates dissolving more solute in a solution than is possible at normal temperatures. After obtaining a supersaturated solution, it is possible to separate the solute from the solvent through crystallization of the solute. The process of crystallization is initiated when the solution starts to cool down.
As a supersaturated solution contains more solute than the solvent can ordinarily contain, it is very unstable and is highly conducive to crystal formation. To help begin the process of crystallization, only one or two crystals of the solute must be added to the solution as it cools down. This prompts the particles of the solute to separate from the solvent and start forming more crystals around the added crystals.Learn more about Chemistry
Water molecules break bonds and insert themselves between sugar molecules, causing sugar cubes to dissolve in water. The positively charged oxygen ions in water combine with the negatively charged hydroxyl groups in sugar, forming a hydration shell around the sugar molecule.Full Answer >
Baking soda, otherwise known as sodium bicarbonate, has the chemical properties of not being flammable, being easily decomposed by acids, starting to decompose in water solution at approximately 20 degrees Celsius and an increasing alkalinity in solution as it is heated or stirred. Baking soda is used for cleaning and cooking and is effective at putting out certain types of fires.Full Answer >
Vinegar is a water solution; its main component is acetic acid, an organic acid with the formula CH3COOH. Acetic acid is a colorless liquid with a molar mass of 60.05 grams per mole and a density of 1.049 grams per mole. It has a recognizable, pungent smell.Full Answer >
Propane is separated from crude oil during the refining process and extracted from natural gas at a gas processing plant. It is considered a fossil fuel because it was formed from the remains of sea animals and plants. When living organisms die and sink to the bottom of the sea, sand and silt cover them, subjecting the remains to high pressure and heat, which change the chemical makeup.Full Answer >
