What are the colligatory qualities?
A coligative feature is a descriptive characteristic used in the chemistry of the solution. The simplest thing is that the colligative properties are the properties of the solution that depends on the number of solut molecules in the solution, but not the identity of these solutial molecules. There are only a few properties of the solution that are colligative: steam pressure, boiling point, freezing point depression and osmotic pressure. Collective properties are defined only for ideal solutions. For example, if a little table salt is dissolved in the water, the salt is a solve and the water is a solvent. The colligative properties of this solution are properties that depend only on the number of salt molecules or the ratio of the number of salt molecules to the number or solvent molecules. The colligative properties of the solution do not depend on the on the latter that solut is salt or on one of the salt properties. A colligative feature is a feature that will behave in the same way for any solution, whether the solution contains salt, sugar or any other possible dissolution.
of four colligative properties of solution, vapor pressure, increased point of boiling and depression of freezing points is closely related. The pressure of vapor as a coligative assets is described according to Raoult's law. In principle, Raoult's law states that for the ideal solution the pressure of the total solution of the total steam pressure depends on each of the chemical components, as well as the mole of each of the chemical components in the solution. More practically, this relationship means that when adding solut to the solution, the change of vapor pressure depends only on the ratio of the solut to the solvent by molecules. Once again, because it is a colligatory feature, the change in steam pressure does not depend on the identity of the dissolved substance.
Increasing boiling point and depression of freezing points are a colligatory characteristics that any change in tandem with vapor pressure changes. When solut is added to the solution, the solutes reduce the pressure of the solvent. Changing pressure causes a corresponding increase in boiling point and decreased the point of freezing. HerIn this words, when it is dissolved into the solution, the solution is now boiled at a higher temperature and freezes at a lower temperature.
osmotic pressure is the fourth coligative feature of the solution. Osmosis is defined as the movement of solvent molecules through a semi -permeable membrane into an area that contains a higher number of soluta molecules. The osmotic pressure is the amount of pressure that needs to be applied to one side of the semi -permeable membrane to prevent the solvent. The Osmotic Pressure ideal solution at constant temperature is proportional to the concentration of solut or other way, depending only on the number of solut molecules.
Collective properties of the solution may seem complicated to define, but can be intuitively understood through several common examples. Many cooks add salt to a pot full of water while cooking pasta, causing faster pasta cooking. This event uses a colligatory feature. Adding salt increases the boiling point of water, allowing pasta to cook faster at higher tEplota water.
freezing depression is also commonly used by chefs. Sugar and salt like soluts help ice cream in freezing. Sugar in ice cream affects the temperature at which the ice cream freezes, and salt water around the ice cream container creates a cooler environment in which the ice cream freezes faster.
