Explain why the vapor pressure boiling point and freezing point of an aqueous solution if a nonvolatile solute are not the same as those of the pure solvent?

The presence of a nonvolatile solute in an aqueous solution lowers the vapor pressure of the solution, raising its boiling point and lowering its freezing point compared to the pure solvent. This occurs due to the solute molecules occupying space at the surface of the solution, reducing the number of solvent molecules escaping into the vapor phase. As a result, a higher temperature is needed to reach the same vapor pressure as the pure solvent for boiling, and a lower temperature is needed for the solution to freeze.


What is the liquid in an aqueous solution?

Aqueous refers to water, so the liquid in an aqueous solution is water.


What evaporates water from an aqueous solution containing a precipitiate?

Heating contribute to the water evaporation.


Name one compound containing large anions which can be used for precipitation of potassium ions from aqueous solution?

Sodium tetraphenylborate (NaB(C6H5)4) is a compound containing large anions that can be used to precipitate potassium ions from aqueous solution. When added to a solution containing potassium ions, insoluble potassium tetraphenylborate precipitates out.


Is carbon dioxide a aqueous solution?

No, carbon dioxide is a gas at room temperature and pressure and does not dissolve readily in water to form an aqueous solution. However, carbon dioxide can react with water to form carbonic acid, which is a weak acid and can exist in an aqueous solution.


Water is a solvent in a(n) what solution?

'An Aqueous' solution. NB The word 'aqueous' comes from Latin ; 'aqua' meaning 'water'.


What is the term for a solution made in water?

The term for a solution made in water is an aqueous solution.


What is the meaning of 50 percent NaOH aqueous solution?

A 50% NaOH aqueous solution means that the solution contains 50% sodium hydroxide (NaOH) by weight and the rest is water. This concentration indicates that for every 100 grams of the solution, 50 grams is NaOH.


What is the best definition for the word aqueous?

a: of, relating to, or resembling waterb : made from, with, or by water


Is CuNO3 a gas liquid solid or aq?

CuNO3 can be found as both a solid and as an aqueous solution.


Is copper acetate an aqueous solution or a gas?

Copper acetate is a solid compound which can be either dissolved to form an aqueous solution, or if sufficiently heated will become a gas.


How will the vapor pressure of pure water compare to an aqueous solution of sodium chloride?

The vapor pressure of pure water will be higher than that of an aqueous solution of sodium chloride at the same temperature because the presence of sodium chloride reduces the number of water molecules available to evaporate, lowering the vapor pressure of the solution. In other words, the solute particles in the solution interfere with the evaporation of water molecules, resulting in a lower vapor pressure compared to pure water.
