Stephanie: "guest", Nicholas When salt is added is because the salts particles __dissociate__ into Na+ and Cl- __ions__ causing more change on __colligative properties__(particle dependent properties) such as the __freezing point depression__ where the number of particles has a greater impact on keeping the ice cool, as a result the ice melts. Melting of ice is and __endothermic__(absorbing energy) reaction so lowering of the freezing point slows down the process making the ice cooler and helps the form the ice cream
