Explain why a common ion lowers the solubility of an ionic compound

From Le Chatelier's principle, that happens to the solubility of a slightly soluble ionic compound when a common ion is added and The solubility of a slightly soluble ionic compound decreases. MX ---> M+ + X-

If you now have some other ionic compound such as QX, this will dissociate to Q+ + X-

Here, the common ion is X. This will push the reaction of MX ---> M+ X- back to the left because of adding more X-. This results in decrease in solubility.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
