CHE 1301 Lecture Notes - Lecture 7: Ionic Compound, Spectator Ion, Aqueous Solution
Document Summary
Formation of a gas oxidation = losing electron(s) reduction = gaining electron(s) Precipitation = a reaction in which a solid forms is called a precipitation reaction. Strong electrolytes = substances that completely dissociate into ions in solution. Insoluble/slightly soluble mean only a tiny amount dissolves that is undetectable with the naked eye. Ionic compounds in water-usually dissociate into component ions. How to predict precipitates when solutions of two ionic compounds are mixed: write the reactants as they actually exist before any reaction occurs. Remember that when a salt dissolves, its ions separate: consider the various solids that could form. To do this, simply exchange the anions of the added salts: use the solubility rules to decide whether a solid forms and, if so, to predict the identity of the solid. Types of equations for reactions in aqueous solutions: molecular equation. Shows the complete formulas of all reactants and products.
