FAQs

What is a non-volatile solute directly proportional to?

A non-volatile solute is directly proportional to its concentration in the solution when considering Raoult’s Law.

Is Raoult’s Law only for non-volatile solute?

Raoult’s Law is typically applied to solutions containing non-volatile solutes, although it can also be used for volatile solutes in certain cases.

What is a non-volatile solute?

A non-volatile solute is a substance that does not readily evaporate at normal temperatures and pressures. Examples include sugar (sucrose) and salt (sodium chloride).

What is the molar mass of a non-volatile solute whose 2% aqueous solution exerts?

Without specific values provided, it’s not possible to calculate the molar mass of the non-volatile solute using Raoult’s Law.

What is Raoult’s Law in layman’s terms?

In simple terms, Raoult’s Law describes how the presence of a solute affects the vapor pressure of a solvent. It states that the vapor pressure of a solution will be lower than that of the pure solvent due to the presence of the solute molecules.

What is the Raoult’s Law in simple words?

Raoult’s Law tells us that when you add a non-volatile solute to a solvent, the vapor pressure of the solution decreases compared to the pure solvent.

What is the simple Raoult’s Law?

The simple interpretation of Raoult’s Law is that the vapor pressure of a solution is lower than that of the pure solvent because of the presence of a non-volatile solute.

How do you know if a solute is volatile or nonvolatile?

A solute is considered volatile if it readily evaporates at normal temperatures and pressures, while a solute is nonvolatile if it does not evaporate easily under those conditions.

What are two examples of non-volatile solutes?

Two examples of non-volatile solutes are sugar (sucrose) and salt (sodium chloride).

What happens when a non-volatile solute is added to a solution?

When a non-volatile solute is added to a solution, it lowers the vapor pressure of the solution compared to the pure solvent. This leads to a higher boiling point and lower freezing point of the solution compared to the pure solvent.

What are the limitations of Raoult’s law for non-volatile solutes?

The limitations of Raoult’s Law for non-volatile solutes include:

• It assumes ideal behavior of the solution, which may not always be the case.
• It assumes that the intermolecular forces between solute-solute, solvent-solvent, and solute-solvent are all similar, which may not be true for all solutions.
• It doesn’t account for non-ideal behavior, such as deviations from ideal solution behavior due to molecular interactions.

Is Raoult’s law applicable to all non-volatile electrolytes?

Raoult’s Law is generally applicable to non-volatile solutes, whether they are electrolytes or not, as long as the solution behaves ideally.

Which do not obey Raoult’s law?

Solutions that do not obey Raoult’s Law typically exhibit non-ideal behavior due to deviations caused by strong solute-solute or solvent-solute interactions. Examples include solutions of polymers, mixtures of highly dissimilar substances, and solutions under extreme conditions.

What is considered non-volatile?

Substances that do not readily evaporate at normal temperatures and pressures are considered non-volatile.

What is the difference between volatile and non-volatile?

Volatile substances evaporate readily at normal temperatures and pressures, while non-volatile substances do not.

Is salt non-volatile?

Yes, salt (sodium chloride) is a non-volatile substance because it does not readily evaporate at normal temperatures and pressures.

Does Raoult’s Law work for volatile solute?

Raoult’s Law primarily applies to solutions with non-volatile solutes, but it can be adapted for solutions with volatile solutes under certain conditions, such as low concentrations.

What is the Raoult’s law for non-volatile solute and non-volatile solvent?

Raoult’s Law for a solution containing both non-volatile solute and solvent states that the vapor pressure of the solution is proportional to the mole fraction of the solvent.

What is Raoult’s law for a solution of 2 volatile liquids?

For a solution containing two volatile liquids, Raoult’s Law states that the partial vapor pressure of each component in the solution is proportional to its mole fraction in the solution.

How do you find the molar mass of a non-volatile solute?

The molar mass of a non-volatile solute can be determined using Raoult’s Law and measurements such as boiling point elevation or osmotic pressure.
