A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What factors determine solubility of a substance?
There are several factors:1) the polarity of the substance and the polarity of the solvent (like dissolves like).2) the temperature of the solvent (for solids, the higher the temperature of the solvent, the higher the solubility -- sugar in hot tea dissolves more easily than in iced tea -- but often for gases, the solubility goes down at higher temperature -- and why soda goes flat when its warm).3) Pressure also effects solubility. Notice CO2 will form bubbles when you open the cap of a soda can. A side note.....the size of the particles and whether or not you stir the solution will help speed up the dissolving process, but it will notchange the total amount that can be dissolved (whereas #1 and #2 do affect the total amount dissolved)Lesson 4: Colligative Properties of Solutions:a.

If water has become saturated will it continue to dissolve salt?
No, but the higher the liquid temperature, the higher the saturation point and the more salt that can be dissolved.
What has a higher blood pressure the aorta or vena cava?
The arterial system generally has a higher pressure than the venous system, so the answer is the aorta. Pressure is lost when the arteries split into capillaries, which have leaky walls.
What is the relationship of the partial pressure of a gas and its diffusion rate?
The higher the pressure, the more easily a chemical diffuses. And seeing as pressure and temperature are directly related, the higher the temperature the more easily a chemical diffuses, and vice versa. This is caused by everything "wanting" to be equal, if there is a higher pressure, then it will diffuse to an area of lower pressure.
What do you mean by concenteration in chemistry?
It refers to the amount of solute dissolved in a solvent. Say, for example, you were making a salt water solution. The higher the amount of salt dissolved in the water, the higher the concentration of the solution.
How would you expect the intrinsic volume for a polymer in a particular solvent to vary with temperature?
generally, a polymer gets dissolved in a solvent (which implies lower density and higher volume). the higher the temperature, the quicker the process, so to answer: the intrinsic volume for a polymer in a particular solvent increases with the temperature.
A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
What is the diffrence between osmosis and diffusion?
Diffusion is the spreading of a substance in another substance effected by the thermal movements of the molecules or other forces acting between the molecules. The spreading happens from an area with high density into areas with originally lower density. For osmosis to occur you must have a solvent in two rooms separated by a membran that lets the solvent molecules pass. In one of the rooms there is a dissolved substance that cannot pass the membrane in a higher concentration than in the other room. This makes solvent pass over to the room with the highest concentration of the substance so that the pressure gets higher in that room and the solution gets less concentrated. The process stops when the pressure is high enough or the concentration of the dissolved substance is equal in both rooms. The mechanism behind osmosis is as follows: The solvent molecules are always moving because of their termal kinetic energy and are steadily colliding with each other and also with molecules of the dissolved substance. All the time some solvent molecules pass through the membran between the two rooms also, and in both directions. But the dissolved substance will all the time collide with some of the solvent molecules and block their passage through the membran. Solvent molecules in the room with most dissolved substance will however be blocked more often from passing than solvent molecules in the other room. Thus there will be most passings from the room with the least dissolved substance.
Which lake have a higher elevation or a lower elevation to dissolved mineral?
Higher elevation is going to also have higher atmospheric pressure. My recollection is that the higher pressure of the atmosphere on the surface of the lake will cause a higher level of absorption in the lake itself.
What is the Relationship of solute concentration and solvent concentration?
These words are the two parts of dissolution. A solute is what is being dissolved, and a solvent is what dissolves it. The most universal solvent is water, which means that most solutes can be dissolved into it. A solute (e.g. sugar) is dissolved in a solvent (e.g. water) to make a solution - sugar solution
Why water and dissolved substances leave the arterioles end of the capillary and enter the venule end?
Water and dissolved substances leave the arteriole end of the capillary due to hydrostatic pressure being higher than osmotic pressure and enter the venule of the capillary due to osmotic pressure being higher than hydrostatic pressure.
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.
How can you create a more concentrated solution?
You'll need to remove solvent somehow; most likely by evaporation if the solvent has a higher vapor pressure than the solute.
What is dilute solution and concentration?
A dilute solution is a solution in which there is a small amount of solute (the thing that gets dissolved) compared to the total amount of possible solute that can be dissolved in the solvent (the thing that does the dissolving). A concentrated solution is when there is a lot or all solute that can possibly fit in the solvent.
True or false The vapor pressure of 1 m sucrose is higher than the vapor pressure of 1 m NaCl where the solvent is water?
maybe
How can dissolved air be removed from water?
Two methods by which you could remove gases that are dissolved in water are pressure reduction and heating. Pressure reduction uses the fact that the gas follows Henry's Law (amount of dissolved gas in a liquid is proportional to its partial pressure). Reducing pressure makes the dissolved gas less soluble. Heating uses the fact that the higher the temperature becomes, the less a gas dissolves, as long as it does not react with the solvent. Heating can expel gas from a solution.
