How does the presence of a solute affect the freezing and boiling points of a solvent?

They usually lower freezing points, think antifreeze.
And salt water freezes at a lower temp than fresh, that is why they put salt on ice.
And they raise boiling points, think salt in water when making spaghetti.
Or, again antifreeze.

∙ 13y agoThe addition of solutes to a nonvolatile solvent to a volitile solution causes an a boiling point elevation and a melting point depression, while also influencing osmotic pressures. These properties can be attributed to the solutes effects on the chemical potentials of the gaseous, liquid and solid phases.

∙ 13y agoSalt water has a different freezing point than regular water. Celsius was modeled after the freezing and boiling points of water and Fahrenheit was modeled after the freezing and boiling points of salt water. They are very different measuring scales which means that a solute(salt) can change the freezing and boiling points of a solvent(water).

∙ 9y agoSolvents can lower the freezing point by adding pressure to the solvent. When the solute expands, it adds to the pressure in the solvent. By adding pressure to the water, it lowers the freezing point. A solute can also lower the freezing point by adding more molecules to the number molecules that are already present in that solvent. This means that the number of molecules in the solute plus the molecules in the solvent makes the solution more dense which makes it take longer to freeze. For example, if you add salt to water, it will lower the freezing point. This is because the molecules in the salt were added to the molecules in the water.

Boiling points are elevated - salt is often added to boiling water when cooking - it is NOT just for flavor

A non volatile solute in a volatile solvent increases the boiling point and decreases the freezing point.

Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Atmospheric pressure and the presence and concentrations of solutes affect the freezing point.
Does salt affect the temperature of water -boiling point - freezing point?
i would opt for the Freezing point. salt decreases the freezing point of water. so if water would normally freeze at 0C, saltwater would freeze at -3C.
How do different solutes affect boiling point?
When a solute is added to a solvent, the boiling point is raised according to the equation ΔTb=Kbm. Thus, the boiling temperature of a solution can be described by: Tb(solution)=ΔTb + Tb(pure solvent). However, for the purposes of this question, adding a solute increases the boiling point of a solution.
What affect does a solid nonionizing solute have on the freezing point of a solvent?
The addition of some solids can lower the freezing point of a liquid, a principle used when salt is applied to melt ice on frozen surfaces. (Britanicca Encyclopedia)
What affects freezing point?
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
raise its freezing point
What ingredients in salt makes water's boiling point lower?
It's not the ingredients in salt, but the presence of the salt itself. The salt holds the water in because of its attractive forces and blocking of the water throughout the mixture. Any soluble substance will affect the boiling and freezing points of any solvent based on how big the solute particles are, and the boiling/freezing pt constants, K, for the solvent.
What are two ways that solutes affect the properties of solvent?
Solutes lower the freezing point and raise the boiling point of a solvent! :)
How does the presence of dissolved sodium chloride affect the boiling and freezing point of water?
Dissolved solute (NaCl, salt) will raise the boiling point and lower the freezing point of water. This is known as a colligative property.
How do altitude affect freezing melting and boiling points of water?
The boiling point of water is lower at high altitude; the freezing point is practically not affected.
How a similarities and dissimilarities of solute and solvent affect the boiling point of solution?
solute is which we are mixing and solvent is that in which we are mixing solute
How does the effect of freezing differ from the effect of boiling the enzyme?
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
How does the addition of solute affect freezing and boiling point and vapor pressure on a solvent?
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
Does mass affect freezing point?
Well, I did an experiment in class on this question. We used different amounts lauric acid and it turned out that the freezing point was pretty much the same for all the samples. So, in all, the freezing point does not depend on the mass of a substance.
How does salt affect the melting and freezing point of water?
Salt decreases the freezing point of water and increases the boiling point of water.
Freezing point is the point at which a liquid turns into a solid What effect can change the freezing point?
Atmospheric pressure and the presence and concentrations of solutes affect the freezing point.
What are different solids that affect the freezing and boiling point of water?
Any solid that is soluble in water.
