Which of the following statements is generally TRUE?

a. The solubility of a solid is highly dependent on both pressure and temperature.

b. The solubility of a solid is highly dependent on pressure.

c. The solubility of a solid is not dependent on either temperature or pressure.

d. The solubility of a solid is highly dependent on temperature.

e. None of the above.

The correct answer is option d, that is, the solubility of a solid is highly dependent on temperature.

Solubility refers to the maximum amount of a component, which will get dissolved in a given concentration of solvent at a particular temperature. The temperature influences the solubility of both gases and solids. The temperature has a direct influence on solubility.

For most of the ionic solids, enhancing the temperature elevates how briskly the solution can be formed. With the increase in temperature, the movement of the solid particles takes place briskly that enhances the chances that they will associate with the majority of the solvent particles. This leads to enhancing the rate at which the solution takes place.
