Best Answer

Impurities dissolved in a liquid will increase the boiling point because they form chemical bonds with the solvent in which they are dissolved, which have to be broken by the addition of heat energy before the liquid can boil. In other words, they are like cement, holding the material together in liquid form.

Volatile impurities can increase the boiling point of a substance through the phenomenon of boiling point elevation. When a non-volatile solute is added to a solvent, it lowers the vapor pressure of the solution, requiring a higher temperature to reach the vapor pressure equal to atmospheric pressure to boil. As a result, the boiling point of the solution is higher than that of the pure solvent.

What is volatile impurity?

Volatile impurity refers to a substance that can easily evaporate or vaporize at room temperature, potentially contaminating the surrounding environment. These impurities can be harmful if inhaled or ingested, making their presence a concern in various industries including manufacturing, pharmaceuticals, and food processing. Regulatory guidelines often set limits on the acceptable levels of volatile impurities to ensure product quality and safety.


How can the boiling point of a liquid be raised without adding soluble impurity?

The boiling point of a liquid can be raised without adding a soluble impurity by increasing the pressure applied to the liquid. This increase in pressure results in a higher boiling point because it requires more energy to overcome the greater pressure and reach the vapor pressure of the liquid.


Water has a boiling point of 100 c while sodium chloride has a boiling point of 1465 c. which of the two substances above is more volatile?

Water is more volatile than sodium chloride because it has a lower boiling point. Volatility refers to how easily a substance changes from a liquid to a gas at a lower temperature.


Does sugar affect the boiling point of water?

Adding sugar to water will raise its boiling point slightly, but the effect is minimal. The increase in boiling point is not significant unless a large amount of sugar is added.


What are the boiling points of volatile compounds?

The boiling points of volatile compounds will vary depending on the specific compound. Generally, volatile compounds have low boiling points, typically below 100°C. Some examples of volatile compounds with low boiling points include ethanol (78.3°C), acetone (56°C), and diethyl ether (34.6°C).

Can a volatile impurity increase the boiling point of a substance?

No, a volatile impurity will lower the boiling point of a substance by disrupting the uniformity of the liquid phase. This causes the solution to boil at a lower temperature compared to the pure substance.


What happens to the melting and boiling point of a substance if it contains impurity?

If the impurity has a higher boiling point then the boiling point of the mixture will also be slightly higher, and vice versa.

How can we use the boiling point of a liquid to decide if the liquid is pure?

on adding non-voatile substance there in an increase in bp of substance...for instance water with a non-volatile solute will h boiling point greater than 373K


What is the effect of soluble volatile substance on the boiling point of a water solution?

A soluble volatile substance will lower the boiling point of a solution. The volatile substance will boil at a lower temperature than the water component, thus causing the solution to boil at a lower temperature.


What do you call a substance that evaporates easily?

A substance that evaporates easily is called volatile. Volatile substances have low boiling points and readily transition from a liquid to a gas at normal temperatures.


What is the effect of a soluble and nonvolatile impurity on the boiling point of a liquid?

A soluble nonvolatile impurity increases the boiling point of a liquid because it disrupts the intermolecular forces between the solvent molecules, making it more difficult for the liquid to vaporize. This phenomenon is known as boiling point elevation.


If you increase the pressure the boiling point will increase or remain same?

If you increase the pressure, the boiling point of a substance will increase. This is because higher pressure leads to stronger intermolecular forces, requiring more energy to overcome them for the substance to boil.


What is non volitile solute?

A non-volatile solute is a substance that does not easily vaporize at normal temperatures and pressures. Non-volatile solutes increase the boiling point and decrease the vapor pressure of a solvent when dissolved in it. Common examples include salts, sugar, and various organic compounds.


What is the process of purifying volatile substances?

The process of purifying volatile substances involves separating them from impurities through methods like distillation, which takes advantage of differences in boiling points. The volatile substance is heated to its boiling point, vaporized, and then condensed back into a liquid form. This helps remove impurities and separate the substance based on its volatility.

The boiling point of a liquid can be raised without adding a soluble impurity by increasing the pressure applied to the liquid. This increase in pressure results in a higher boiling point because it requires more energy to overcome the greater pressure and reach the vapor pressure of the liquid.


How does one increase the melting or boiling point of a substance?

Add impurities (salt and others) to the substance.
