A substance that gives off heat when dissolving in water will

have greater solubility at low temperatures. According to Le Chatelier's

Principle - if heat is a product of the reaction, increasing the

temperature will drive the reaction backwards.

The solubility of Na2SO4 decreases with increasing temperature because the dissolution of Na2SO4 in water is an exothermic process, meaning it releases heat. According to Le Chatelier's principle, increasing the temperature will shift the equilibrium towards the reactants' side, resulting in less solute being dissolved in the solution.

It does increase. The temperature is increased, so more solute particles will dissolve. This occurs because as the temperature increases, the intermolecular forces can be more easily broken, allowing more of the solute particles to be attracted to the solvent particles.

It is because the soulubility is changed physically. In actuality the solubility of na2so4 increases but as temp increases the solubity aslo decreases. So really it is like the solubility of the chemical decreases more during the thermal increse than the increase of solubility.

I believe (I may be wrong) because it's a gas.

Does solubility increase or decrease if temperature increases?

Solubility of solid solutes generally increases with increasing temperature, as higher temperatures provide more energy for solid particles to break apart and separate into the solvent. However, solubility of gases in liquids typically decreases with increasing temperature, as higher temperatures decrease the gas solubility due to lower gas solubility constants.


Why is temperature usually stated when solubility's and densities are given?

Temperature affects the solubility and density of a substance. Solubility generally increases with temperature for solids in liquids, while it generally decreases with temperature for gases in liquids. Temperature also affects the volume of a substance, which in turn influences its density. Therefore, temperature is often included when stating solubility and density values to provide a complete picture of the conditions under which these properties were measured.


What happens to solubility as the temperature changes?

Generally, the solubility of solids increases with an increase in temperature, while the solubility of gases decreases with an increase in temperature. This is because higher temperatures usually provide more energy for solvent molecules to break apart solute particles and form a solution.


Is pentanol water soluble?

The OH group makes it slightly water soluble while the carbon group resists solubility. The 3-pentanol molecule is slightly water soluble.


Does the solubility increase as the temperature increases?

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.

Can heat change the solubility?

Yes, heat can change the solubility of a substance. In general, an increase in temperature usually increases the solubility of solid solutes in liquids, while the solubility of gases in liquids decreases with increasing temperature.


Why does the solubility of NaCl remain nearly constant and the solubility of Na2SO4 decrease and temperature increases?

NaCl is a simple ionic compound that dissociates into Na+ and Cl- ions, leading to an increase in solubility with temperature due to the increased kinetic energy of the particles. In contrast, Na2SO4 forms complex ions in solution that are less stable at higher temperatures, which decreases its solubility.


Does the solubility of gases increase with temperature increase?

Yes, the solubility of gases generally decreases with an increase in temperature. This is due to the fact that as temperature rises, the kinetic energy of gas molecules also increases, making it easier for them to escape from the liquid.

What happens to the velocity as the height increases?

As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.
