Net Ionic Equations
Net ionic equation - includes only those compounds and ions that undergo a chemical change in a reaction in an aqueous solution.
Spectator ions - ions that do not take part in a chemical reaction and are found in solution both before and after the reaction

18. Chapter 13 Strong Electrolytes
Section 1 Compounds in Aqueous Solution
Chapter 13
Strong Electrolytes
Strong electrolyte - compound whose dilute aqueous solutions conduct electricity well
Contains all or almost all of the dissolved compound in the form of ions.
To whatever extent they dissolve in water, they yield only ions.
HCl, HBr, HI
All soluble ionic compounds

19. Chapter 13 Weak Electrolytes
Section 1 Compounds in Aqueous Solution
Chapter 13
Weak Electrolytes
Weak electrolyte - compound whose dilute aqueous solutions conduct electricity poorly
Contains a small amount of the dissolved compound in the form of ions.
