Electrolytes are compounds that can conduct electricity once they are dissolved in a solvent. 

Understanding Electrolytes

Whenever you add a solute to a solvent there are three possible outcomes: the solute dissolves completely, dissolves partially or doesn't dissolve at all into ions. 

Concept #1: The Classification of Strong Electrolytes

Strong Electrolytes break up into ions completely and are grouped into 3 categories: Strong Acids, Strong Bases and Soluble Ionic Compounds

Example #1: Provide the equation when sulfuric acid dissolves in a solvent.

Concept #2: Strong Bases represent strong electrolytes that complete dissolve into ions in a solvent. 

Practice: Which of the following represents a strong base?

Concept #3: Weak Electrolyte Classifications

Weak Electrolytes partially break up into ions and are grouped into 2 categories: Weak Acids and Weak Bases

Example #2: Which of the following represents a weak binary acid and therefore a weak electrolyte? 

a) H2SO3                      b) HCl                          c) HNO2                       d) HCN                                    e) HBrO3

Concept #4: Nonelectrolytes are covalent compound that don't dissolve into ions. 

Non-Electrolytes do NOT break up into ions at all and are commonly referred to as molecular compounds

Practice: Which of the following represents a non-electrolyte? 


Practice: Each of the following reactions depicts a solute dissolving in water. Classify each solute as a strong electrolyte, a weak electrolyte or a non-electrolyte.


Practice: Which of the following statements is true?
