Chapter 4 Aqueous Reactions and Solution Stoichiometry General properties of Aqueous Solutions Electrolytic Properties Solutes dissolve in solvents Electrolyte-conducts electricity and contains ions Nonelectrolyte doesn’t conduct electricity and doesn’t have ions Ionic Compounds in Water Ions ‘break’ apart in water, stabilizes ions Molecular Compounds in Water Mostly nonelectrolytes Strong and Weak Electrolytes Strong electrolytes exist nearly completely as ions in solution Weak electrolytes exist mostly in form of molecules Double arrow used for weak electrolytes, single for strong Soluble ionic compounds are strong electrolytes Precipitation Reactions Solubility guidelines for Ionic Compounds All common ionic compounds of the alkali metal ions (group 1A) and ammonium ion are soluble in water Exchange (Metathesis) Reactions AX + BY = AY + BX Complete ionic equation Net ionic equation If every ion in a complete ionic equation is a spectator then no reaction occurs Don’t break up precipitate on product side of equation Acid-Base Reactions Acids
