CH 111 - Introduction to Inorganic and Organic Chemistry Lab 10 - Exp. 341 Synthesis of Strontium lodate In this lab, we will perform a synthesis reaction to generate a desired product. Synthesis reactions are performed in many different industries including fertilizers, plastics, pharmaceuticals and many others. The goal in a synthesis reaction is to generate and obtain as much of the desired product as possible. In this synthesis, the reaction between KIO, (potassium iodate) and Sr(NO3)2 (strontium nitrate) produces...
