Adding salt to water increases the boiling point of water due to a fundamental colligative property of matter known as boiling point elevation. Whenever a solute, such as salt, is added to a solvent, such as water, the boiling point becomes higher than that of the pure solvent. This phenomenon occurs for all solute-solvent systems, regardless of interactions between the solute and solvent molecules.Know More
The reason why the boiling point rises when solute is added to a solvent has to do with vapor pressure. A liquid boils when its vapor pressure is equal to that of the atmosphere. Vapor pressure of a solution increases as it is heated. At standard temperature and pressure, the vapor pressure of a solution is always lower than that of a pure liquid, and thus a solution must reach a higher temperature before it boils.
The degree of boiling point elevation is dependent on the amount of solute added to solution. The larger the number of salt molecules added to a given volume of water, the greater the degree of boiling point elevation. According to About.com, a person would have to add 230 grams of sodium chloride (table salt) to a liter of water in order to increase its boiling point a mere 2 degrees Celsius.Learn More
Acidic solutions turn litmus paper red, turn a universal indicator red or yellow, taste tart or sour, conduct electricity, react with metals, and neutralize bases. When an acid and a metal react, hydrogen is released; when an acid and a base react, an ionic compound called a salt is formed.Full Answer >
Isopropyl alcohol is primarilyÂ synthesized using aÂ direct or indirect process of hydrating propene with water. Both methods involve a further purification technique of distilling the isopropyl alcohol from water and other byproducts.Full Answer >
A hypertonic environment is one in which the concentration of a solution's dissolved substance is greater than the concentration of the dissolved substance in the solution compared. If a cell is placed in a hypertonic environment, the cell membrane works to achieve equal concentrations on each side of the membrane.Full Answer >
Baking soda, also known as sodium bicarbonate, is highly soluble in water. This means that it can easily be dissolved in water but can also be fully recovered when the water is evaporated.Full Answer >
