How does temperature affect the amount of solute that can dissolve in a amount of solvent?

Answer 1

For the solute to be soluble the solvent must first break the existing bonds between the solute. Increasing heat energy breaks more of the existing bonds of the solute which allows the solvent to make more new bonds with the solute particles. This leads greater solubility of the solute in the solvent.

(I don't think this applies if gas is the solute and solvent)

Answer 2

In short, the higher the temperature of the liquid solvent, the more soluable the solute.

Let's look at something familiar. How about sugar in tea, which is to say sucrose in water?

If you have a cup of hot tea, the molecules of the water are moving much faster due to higher kinetic energy from the heat, so there is more room between them for dissolving the sugar, and it's easy to dissolve two teaspoons of sugar (or even more) completely in the tea without any sugar precipitating out, and the more sugar we dissolve, the sweeter the tea tastes.

Take that same volume of iced tea. Now the water molecules have low kinetic energy due to colder temperature and they are packed together much tighter, and there is less room between them to dissolve the sugar. If we try to dissolve two teaspoons of suger in iced tea, most will precipitate out to the bottom of the glass and no matter how hard we stir, the tea does not get sweeter. This is called a super saturated solution.

If you like your iced tea sweet, make it first as hot tea and dissolve the desired amount of sugar in it. After it is cooled, your sugar solute will not precipitate out because it has already been completely dissolved in the water.

Answer 3

Generally, increasing temperature increases the solubility of most solids in liquids, as it increases the kinetic energy of particles causing them to move more and break down the solute particles easier. However, it may decrease the solubility of gases in liquids, as gases tend to become less soluble in warmer temperatures due to their molecules having greater kinetic energy to escape the liquid solvent.

Answer 4

solublilty is different for each combinatoin of solute and solvent . the amout of different solutes that are needed to saturate a cretain volume of solvent varies enormously

Answer 5

The higher the temperature the faster the solute dissolves and mixes with the solvent substances.

Answer 6

by increasing the temperature we can increase the amount of solute in the given solvent
