Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
What else can I help you with?
What happens to a solvent when a nonvolatile solute is added to it?
It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.
What happens when a base dissolve?
It increases the concentration of OH - in a solution.
What happens to the freezing temperature of a solution of table salt in water as the solution becomes more concentrated?
As concentration of a solute (like table salt) in a solvent increases, the freezing point of water lowers. The vapor pressure also decreases, and the boiling point increases. These are known as water's colligative properties.
What happens to concentration of the sugar solution as the water is removed?
Concentration increases
What happens in a buffer when the level of h ions in the solution increases?
it accepts H+ ions
What happens to a solvent when a nonvolatile solute is added to it?
It increases the boiling point of the solution and it increases the temperature range over which the solution remains a liquid.
what happens to the density of a solution as its concerntration increases?
it increases
As the choose... of the solution increases, what happens to the solubility of the salt?
As the temperature of the solution increases, the solubility of the salt also increases.
What happens when a base dissolve?
It increases the concentration of OH - in a solution.
What happens when you add salt to water and how does it affect the properties of the solution?
When salt is added to water, it dissolves and breaks down into ions. This process is called dissociation. The presence of salt in water increases the boiling point and decreases the freezing point of the solution. It also increases the density and conductivity of the water.
What happens as a solution becomes diluted in entropy?
Its entropy increases.
What happens when bases dissolve?
It increases the concentration of OH - in a solution.
What happens to the freezing temperature of a solution of table salt in water as the solution becomes more concentrated?
As concentration of a solute (like table salt) in a solvent increases, the freezing point of water lowers. The vapor pressure also decreases, and the boiling point increases. These are known as water's colligative properties.
What happens to the temperature of a liquid as it changes from a liquid to a vapor?
The liquid vaporizes and the temperature increases as the volume also increases.
What happens to concentration of the sugar solution as the water is removed?
Concentration increases
What happens when a solution increases its acidity?
Its pH value becomes decreased.
What is the relationship between boiling point elevation and freezing point depression in a solution?
Boiling point elevation and freezing point depression are both colligative properties of a solution. Boiling point elevation occurs when the boiling point of a solvent increases when a solute is added, while freezing point depression happens when the freezing point of a solvent decreases with the addition of a solute. These phenomena are related because they both depend on the concentration of solute particles in the solution, with boiling point elevation and freezing point depression being proportional to the number of solute particles present.
