How will the vapor pressure of an aqueous solution of sodium chloride compare to that of pure water?
How will the vapor pressure of an aqueous solution of sodium chloride compare to that of pure water?
The vapour pressure of an aqueous solution of sodium chloride will be lower than that of pure water. This is because, dissolution of solute in a solvent always reduces the vapour pressure of the solution as a result of interactions between the molecule of the solute and the solvent.
Is the vapor pressure of a solution of sucrose higher than that of water give reason does sucrose contribute to the total vapor pressure?
Note that the vapor pressure of water decreases as the concentration of sucrose increases. A volatile solute (i.e., a solute that has a vapor pressure of its own) will contribute to the vapor pressure above a solution in which it is dissolved.
What happens when a non volatile solute is added to a solution?
The vapor pressure of a solvent is lowered by the addition of a non-volatile solute to form a solution. This decrease in vapor pressure can be explained by using the entropy differences of the liquid and gas phases along with the position of dissolved particles after the addition of the solute.
What is a pure solvent?
Pure solvent means absence of other substances or impurities. For example From Water and salt solution , Water is pure solvent while because of presence of salt it becomes impure.
Is water a pure solvent?
Water as pure solvent: Water is usually appearing in its pure state, almost a pure solvent, unless distillated. For instance, dissolving of sodium chloride or potassium nitrate in pure water, a pure solvent, lowers the freezing point irrespective of the salt added.
What is the difference between a pure solvent and a solution?
When one substance dissolves into another, a solution is formed. A solution is a homogeneous mixture consisting of a solute dissolved into a solvent . The solute is the substance that is being dissolved, while the solvent is the dissolving medium.
What are two examples of a solute?
Examples of solutes include, sugar, salt, oxygen, etc. There are numerous examples of solutions. For example milk (solvent) and sugar (solute) makes sweet milk. Air is made up of gases (oxygen, nitrogen, carbon dioxide, etc.).
Is alcohol a solvent or a solute?
(NaCl is the solute in this solutions because it changes state when it dissolves.) It is also possible to dissolve gases such as HCl in a liquid to form a solution such as hydrochloric acid….Examples of Solutions.
| Solute | Solvent | Solution |
|---|---|---|
| alcohol | water | wine |
