The Precipitation and Treatment of Calcium Oxalate By: Andrew Bradley and Sam Rosenberg

Abstract

 **CHEMISTRY LAB PROJECT: PRECIPITATION AND TREATMENT OF CALCIUM OXALATE. Andrew Bradley. **The purpose of this lab was to successfully precipitate calcium oxalate crystals, also known as kidney stones, and test different solutions to dissolve the crystals to treat them. Calcium oxalate was investigated for treatment options to breakdown the crystal. The methodology utilized within the experiment was acid base chemistry, working with acidic and basic solutions to first precipitate calcium and oxalate and then to later dissolve it. Theoretic principles include the precipitation of a solid from other soluble reactants within acidic solutions. Unfortunately, not enough lab time was left for the treatment and dissolving of the calcium oxalate crystals in acidic or basic solutions. Ideally, the precipitate would have been tested in acidic and basic solutions to observe which solution was the most effective agent in breaking down the calcium oxalate. In conclusion, this experiment can be furthered to test the breakdown of calcium oxalate in acidic or basic solutions. Those results could be applied to the treatment of kidney stones for future patients with the disease.  //Key words: Precipitation, solubility, acid base chemistry, titration //
