Question

What is the effect of change of temperature on the solubility of a salt?​

Answer 1

Answer:

increases

Explanation:

Solubility often depends on temperature; the solubility of many substances increases with increasing temperature.

Answer 2

Explanation:

Let's us a consider a fixed amount of solvent(water) at constant temperature is provided to us. We have to mix salt to form salt solution and we will have to continue adding more and more till it's get saturated.

• Saturated solution - A solution which at a given temperature dissolves as much solute as it is capable of dissolving which is determined by the solubility of the solute in that particular solution.

After this, we can't add more salt anymore. Salt actually takes place inside the intermolecular spaces in between the water molecules. And when these are filled up, no more salt is dissolved.

Now if we increase the temperature, the molecules will separate from each other and the intermolecular spaces increases. Now, we can add more solute to the solution$.$

So, we can say that,

Due to increase in temperature solubility of the salt increases and decreases when temperature is decreased.

So solubility is directly proportional with the change in temperature. And we are done !!
