The correct statement regarding how temperature changes affect the solubility of salt in water is:
High temperatures mean more kinetic energy, which keeps sodium and chloride ions more separated and in solution, thereby increasing solubility.
As temperature increases, the kinetic energy of the water molecules also increases, which leads to greater agitation and movement of the solvent molecules. This increased motion helps to break apart the ionic bonds between the sodium and chloride ions in the salt, allowing more of them to dissolve in the water. Thus, high temperatures generally lead to increased solubility of salts in water.
