CHEMICAL REACTIONS OBJECTIVES 1. To study reactions
... When two ionic solutions are mixed and there is not an ion combination that is insoluble or gaseous, no reaction will be observed. For example, no reaction occurs between NaCl and KNO3 because all ionic combinations are soluble compounds. Part II. Exothermic and endothermic reactions Reactions that ...
