Answer:
            The solubility of NaCl is least affected by temperature.

Explanation:
                    When any solute is dissolved in water it either releases heat (Exothermic Reaction) or absorbs heat (Endothermic Reaction). This heat absorbed or released is called as Heat of Solution.
                     Heat of solution depends upon heat of ionization (endothermic process) and heat of hydration (exothermic process). When heat of ionization is greater than heat of hydration then the reaction will be endothermic and vice versa.
                     In case of NaCl the heat of Ionization and Heat of Hydrations are almost same. That is why the solubility of NaCl is least effected by temperature.

The solubility of Sodium chloride (NaCl) is least affected by temperature.

What is solubility?

Solubility is define as the ability of a substance to react with other substance completely in the liquid form.

During the process of solubility heat may be released or absorbed which depends on the ionization and hydration process. As heat of ionization is endothermic in nature and heat of hydration is exothermic in nature.

Whenever if in any case both the above heat is almost equal then in that condition solubility doesn't takes place. So, in the case of NaCl both of these heats are equal as a result of which NaCl solubility is less affected.

Hence, NaCl is least affected by temperature.
