What is a titration? How does stoichiometry apply to it?

Learning Intentions

• You will learn about solution stoichiometry and be able to convert volumes of known concentrations into unknown concentrations of substances in other parts of a chemical reaction.

• You will learn what a titration is and what role it plays in solution stoichiometry.

• You will learn that solution composition can be expressed in a variety of ways: molarity is the most common method used in the laboratory. Molarity is defined as the number of moles of solute per liter of solution.

• You will learn how to analyze various titration curves to identify what type of reactions is being graphed and information about substances in the titration curve and various points along the titration.

Closing Task:

You can solve solution stoichiometry problems using data from titrations.

Content Standards being covered:

 LO 3.7 Student is able to identify compounds as Bronsted-Lowry acids, bases and/or conjugate acid-base pairs, using proton transfer reactions to justify the identification.

LO 3.3 The student is able to use stoichiometric calculations to predict the results of performing a reaction in the laboratory and/or to analyze deviations form the expected results.

LO 3.4 The student is able to relate quantities (volumes of solutions) to identify stoichimetric relationships for a reaction including situations involving limiting reactants and situations in which the reaction has not gone to completion.

LO 2.2 The student is able to explain the relative strengths of acids and bases based on molecular structure, interparticle forces and solution equilibrium.

LO 2.9 Student is able to create or interpret representations that link the concept of molarity with particle views of solutions.
