WHAT IS VAPOR PRESSURE? 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) 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 The RAISING of the normal boiling point of a liquid by adding a non-volatile substance to it. When you add non-volatile solute to a pure solvent, the boiling point of the liquid solvent is elevated. This means that the Read More …
VAPOR PRESSURE LOWERING Adding non-volatile solute to volatile solvent lowers the solvent’s vapor pressure. For example, water normally boils at 100 degrees C (212 F) but if you add something like salt to the solution, it decreases the vapor pressure of the solution. The water will only Read More …
WHAT ARE COLLIGATIVE PROPERTIES OF SOLUTIONS? 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 gas or solids. COLLIGATIVE PROPERTIES ARE Read More …
