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 are the 3 factors that affect the solubility of a substance?
The three factors that affect the solubility of a substance are temperature, pressure (for gases), and the type of solvent used. Generally, solubility increases with higher temperatures for solid solutes but may vary for gas solutes. Additionally, the nature of the solvent plays a significant role in determining solubility.
Does air pressure affect dissolving of crystals?
Air pressure can affect the rate of crystal dissolution by influencing the equilibrium between the dissolved and solid phases. Higher air pressure can increase the solubility of gases in the solvent, potentially altering the dissolution process. However, the impact of air pressure on crystal dissolution may vary depending on the specific solvent and crystal system involved.
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 are these factors that affect solubility?
Factors that affect solubility include temperature, pressure, nature of the solute and solvent, as well as presence of any other dissolved substances. Generally, higher temperatures increase solubility for most solutes, while some solutes may exhibit opposite trends. Increasing pressure can also enhance solubility of gases in liquids.
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 can you create a more concentrated solution?
To create a more concentrated solution, you can add more solute (substance being dissolved) to the solvent (liquid medium). This increases the amount of solute particles in the solution, making it more concentrated. Alternatively, you can decrease the amount of solvent in the solution, which also increases the concentration of the solute.
What type of solute is more soluble at higher pressures?
All gasses are more soluble (e.g. in water) at higher pressures.Henri's Law states:A gas law that states that the mass of a gas dissolved by a given volume of liquid at a constant temperature is directly proportional to its pressure.
Why can volatile impurity increase the boiling point of a substance?
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.
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.
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
