Strong Acids and Strong Bases are classified as Strong Electrolytes. While Weak Acids and Bases are Weak Electrolytes.

Understanding Acid and Base Strength

Concept #1: Strong vs Weak Acids

Concept #2: Strong vs Weak Bases

Example #1: The following represent aqueous acid solutions. Identify the strong acid, weak acid and weakest acid.

Concept #3: Strength of Conjugate Bases

Stronger the acid, weaker the conjugate base.

Concept #4: Strength of Conjugate Acids

Weaker the acid, stronger the conjugate base.

Example #2: Which of the following acids have relatively strong conjugate bases?

Practice: Which of the following is the strongest base?

Practice: Which of the following bases will have the weakest conjugate acid?

Practice: Which of the following aqueous species will contain mostly reactants?

Practice: Determine [OH] in each base solution. If the base is weak, indicate the value that [OH] is less than.

Practice: Predict the direction of the following reaction:

HC2H3O2 (aq)  +  H2O (liq)  ______________   H3O+ (aq)  +  C2H3O2 (aq)
