Does a cool solvent dissolve less solute than an equal amount of warm solvent?

I believe heating a solvent in a solution breaks bonds between molecules in the solvent, so the molecules in an excited state can mix with and rebond to other molecules in any other solvent that's added.

∙ 14y agoIt is true for most solvents but in cases when heat is evolved after dissolution of solute,
then solubility decreases on increasing temperature i.e. adding more heat.

The solubility of gases in liquids is increased when the temperature decrease.

How is massed conserved when adding a solute to a solvent?
If you weigh the solute, and then weigh the solvent, and then add the solute to the solvent and weigh the solution, you will find that the sum of the weights of the solute and solvent is equal to the weight of the resulting solution. So mass is conserved.
Why do isotonic solutions have the same pecentages?
Isotonic solutions have equal amounts of solute and solvent which means that the solution is 50% solute and 50% solvent. Solutions which have more or less solute are called hypotonic and hypertonic.
What is the molality of solution?
The number of moles of a solute per kilogram of solvent. (Apex)
If something dissolves into something else will it change mass?
The mass of the solution will be equal to the mass of the solute plus the mass of the solvent. However, the total mass does not change.
The solute molecules mixed with the solvent molecules in a solution cause the of a solution to be higher than it is for an equal volume of pure solvent?
Raoult's Law and Vapor Pressure LoweringWhen a nonvolatile solute is added to a liquid to form a solution, the vapor pressure above that solution decreases. To understand why that might occur, let's analyze the vaporization process of the pure solvent then do the same for a solution. Liquid molecules at the surface of a liquid can escape to the gas phase when they have a sufficient amount of energy to break free of the liquid's intermolecular forces. That vaporization process is reversible. Gaseous molecules coming into contact with the surface of a liquid can be trapped by intermolecular forces in the liquid. Eventually the rate of escape will equal the rate of capture to establish a constant, equilibrium vapor pressure above the pure liquid.If we add a nonvolatile solute to that liquid, the amount of surface area available for the escaping solvent molecules is reduced because some of that area is occupied by solute particles. Therefore, the solvent molecules will have a lower probability to escape the solution than the pure solvent. That fact is reflected in the lower vapor pressure for a solution relative to the pure solvent. That statement is only true if the solvent is nonvolatile. If the solute has its own vapor pressure, then the vapor pressure of the solution may be greater than the vapor pressure of the solvent.Note that we did not need to identify the nature of the solvent or the solute (except for its lack of volatility) to derive that the vapor pressure should be lower for a solution relative to the pure solvent. That is what makes vapor pressure lowering a colligative property--it only depends on the number of dissolved solute particles.summarizes our discussion so far. On the surface of the pure solvent (shown on the left) there are more solvent molecules at the surface than in the right-hand solution flask. Therefore, it is more likely that solvent molecules escape into the gas phase on the left than on the right. Therefore, the solution should have a lower vapor pressure than the pure solvent.Figure %: The Vapor Pressure of a Solution is Lower than that of the Pure Solvent
What happen when solvent is equal to solute?
solution is in equilibrium and the solvent and solute continue diffusion or osmosis at an equal rate.
Alcaligenes faecalis osmatic pressure hypotonic or hypertonic or isotonic?
Hypotonic is a solution that has more solute than solvent while hypertonic is a solution which contains more solvent than solute. Isotonic is a solution where in both solute and solvent are equal in amount.
How is massed conserved when adding a solute to a solvent?
If you weigh the solute, and then weigh the solvent, and then add the solute to the solvent and weigh the solution, you will find that the sum of the weights of the solute and solvent is equal to the weight of the resulting solution. So mass is conserved.
Does the mole of solution is equal to mole of solute plus mole of solution?
No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)
What is the mole fraction of solute and solvent is equal to?
1
What is a solution equal to?
A solution contain a solute dissolved in a solvent.
When a solution is?
when no more solute will dissolve ========== when the concentration of the solute is equal to the concentration that would be in equilibrium with any solid of the same substance - when that happens, no more solute will dissolve, or more precisely, if any more dissolves, it would be expected to cause the same amount to precipitate out, thus keeping the concentration constant.
Why do isotonic solutions have the same pecentages?
Isotonic solutions have equal amounts of solute and solvent which means that the solution is 50% solute and 50% solvent. Solutions which have more or less solute are called hypotonic and hypertonic.
When a solution is saturated?
when no more solute will dissolve ========== when the concentration of the solute is equal to the concentration that would be in equilibrium with any solid of the same substance - when that happens, no more solute will dissolve, or more precisely, if any more dissolves, it would be expected to cause the same amount to precipitate out, thus keeping the concentration constant.
What is it called when the concentration of solute and solvent are equal on both sides of the membrane?
isotonic
What is it called When the concentrate of solute and solvent are equal on both sides of the membrane?
isotonic
When does a liquid gets saturated?
when it is unable to dissolve further soluteWhen the fugacity of the solute in the liquid phase is equal to the fugacity of the undissolved solute
