Product Details

Classic AP Requirement #8—Determination of Concentration by Oxidation–Reduction Titration

Students standardize a solution of potassium permanganate by redox titration with a standard solution of iron(II) ions. They will then take this potassium permanganate solution and titrate it against a solution of oxalic acid. The data will then be used to calculate the exact concentration of the oxalic acid solution. Students gain experience in the process of titration and standardization, writing half reactions and calculating molar concentrations and oxidation numbers.

Complete for 24 students working in pairs.

Performance Expectations

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-7. Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
