How does heating water increase the amount of solute dissolved?

Answer 1

That depends on the solute. If the solute is normally a solid, then heating the solution will make it more soluble, just as solids melt when heated.

If the solute is naturally a gas, on the other hand, then heating the solution will make it less soluble; some may come out of solution, just as liquids evaporate if you heat them enough. That's assuming the fluid is free to expand, i.e. the pressure is fixed. If you do this inside a sealed container of some kind, so that the volume is fixed but the pressure increases when you heat it, the answer may be different, I'm not sure.

Answer 2

Water at ambient(room) temperature undergoes a spontaneous reversible reaction.

H2O < ==> H^+ + OH^-

Like all chemical reactions, when heated , they undergo a degree of thermal decomposition. When water is heated the water molecule dissociates more readily. So More H^+ & OH^- are created.

Since more H^+ & OH^- are created , they will react with more solute. Hence more solute is dissolved.

Answer 3

Every reaction needs energy to proceed . Heating basically provides kinetic energy to the molecules so if heat is added it increases the kinetic energy of molecules as a result more molecules attain maximum energy needed to react and dissolve ,hence heating water increases the solubility of solute in water.

Answer 4

The addition of more heat facilitates the dissolving reaction by providing energy to break bonds in the solid. This is the most common situation where an increase in temperature produces an increase in solubility for solids.

Answer 5

Heating water increases the kinetic energy of the water molecules, allowing them to move faster and more freely. This increased movement helps break the intermolecular bonds between the solute particles, making it easier for the solute to dissolve in the water.

Answer 6

It basically eats at the thing till it can reach the other side.

Answer 7

Yes. Heating water can increase the amount of solute that can be dissolved.
