Product Details

Classic AP Requirement #15—Synthesis of a Coordination Compound and Its Chemical Analysis

Students synthesize the coordination compound potassium trioxalatoferrate(III) trihydrate, K3[Fe(C2O4)3]•3H2O. Once produced, the product is identified by colorimetric methods and the percent yield of the product is determined. The absorbance of a solution of the product will be taken at three wavelengths. The ratios of these absorbances are used to identify the compound in solution as K3[Fe(C2O4)3]•3H2O.  

Complete for 24 students working in pairs.

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
