One becomes hot with water and vinegar and the other is cold with water...that sounds like there's an exothermic reaction with water with the one (vinegar has water in it I believe). Possible there's an endothermic reaction with water with the other one; did the solution get colder when the solid was mixed in or did it just stay cold?
