Does the solubility increase as the temperature increases?

Answer 1

Perhaps you mean the solubility of substances in water. Most solids have increasing solubility in water with increase in temperature, but certainly not all of them. Some solids e.g. Cerium Sulphate have decreased solubility in water at higher temperatures, while some solids show increasing solubility up to a certain temperature, above which the solubility decreases, such as Sodium Sulphate. The solubility of common salt, Sodium Chloride, is almost unaffected by temperature. Gases generally have lower solubility in water at higher temperatures.

Answer 2

It depends on what substance you are talking about, if it is a solid you are dissolving, than rising the temperature will increase the rate of dissolving. if it is a gas you are dissolving, than no lowering the temperature will increase the rate.

Answer 3

The solubility of most but not all salts increases with increasing temperature of the solution. If the dissolution of the solute is strongly exothermic, as with calcium oxide, the solubility decreases with temperature. Sodium chloride's solubility is little changed with temperature. If the dissolution of a salt is endothermic, the solubility of that salt will increase with temperature, and the dissolution of most salts is at least mildly endothermic.

Answer 4

In general, solubility of solids in liquids tends to increase as temperature increases, due to the increased kinetic energy of molecules which helps break down the bonds in the solid. However, for gases dissolved in liquids, solubility typically decreases with increasing temperature, as higher temperatures reduce the gas-liquid interaction strength.

Answer 5

No. There are a few compounds, such as cerium sulfate, for which the solubility goes down as temperature increases.

Answer 6

Solubility limits definitely increase with temperature if talking about molten metals. There are phase diagrams for most materials that provide solubility limits at various temps.

Answer 7

yes
