Coordination Compound Synth

Lab Summary

Use a series of reactions to synthesize a coordination compound, potassium aluminum sulfate dodecahydrate (alum), and calculate the theoretical and percent yields.

Theory

Students synthesize a coordination compound, potassium aluminum sulfate dodecahydrate (alum), and calculate the theoretical and percent yields.

Method

Students gain experience conducting the following procedures:

  • Carrying out a series of reactions that result in the synthesis of alum.
  • Practicing laboratory techniques.
