    Learning Objectives

    After completing this exercise, students will be able to:

    • Write the neutralization reaction between an acid and base.
    • Determine if a neutralization reaction goes to completion.
    • Calculate the equivalence point of a titration.
    • Use stoichiometry to determine the dominate species present after a neutralization reaction.
    1. Develop a guideline for when the reaction between a weak acid and strong base goes to completion based only on the Ka of the weak acid.

     

     

     

     

     

     

     

     

     

     

    1. A 0.219 g sample of primary standard grade Na2CO3 (FM = 105.988 g/mol) is dissolved in 25.0 mL of water. Calculate the first and second equivalence points if the solution is titrated with 0.106 M HCl.
