Water always evaporates no matter what the temperature or atmospheric pressure is. Even in the coldest of winter, snow and ice can evaporate by a process called sublimation. They can turn straight into vapor (the gaseous stage) without melting. The Read More …
Freezing point depression is simply the process of LOWERING the freezing point of a liquid by adding a solute to it. Adding non-volatile substance to volatile substance lowers the temperature for freezing point.
Boiling point elevation is the elevation of a solid’s normal boiling point by adding a substance to it. When you add a solute (such as salt or sugar) to a pure solvent (such as water), the boiling point of the Read More …
Adding a solute to a pure solvent lowers the solvent’s vapor pressure. For example, water normally boils at 100ºC (212ºF) but if you add a substance like salt to the solution, it decreases the vapor pressure of the solution. First, recall Read More …
The characteristics of a solution such as the boiling point, freezing point and vapor pressure are known as colligative properties. Colligative properties apply only to solutions and not gases or solids. COLLIGATIVE PROPERTIES ARE DEPENDENT ON THE NUMBER OF ATOMS Read More …
