TA Name:
Purpose: The purpose of the lab was to show the application of stoichiometry in predicting
quantities of reactants and products in chemical reactions, focused on determining the percent
oxygen released during thermal decomposition of potassium chlorate (KClO3). Additionally,
the experiment aimed to calculate the percent potassium chlorate present in an unknown
mixture containing KClO3 and KCl.
Procedure:
1. Two Pyrex test tubes were obtained and labeled as No. 1 (KClO3) and No.2
(unknown) using green tape at the top of each test tube.
2. A small amount of manganese dioxide (MnO2) was added to each test tube to cover
the bottom.
3. The test tubes were gently heated over a Bunsen burner for 1-2 minutes to remove any
moisture.
4. Before any substances were added, the initial weight of each test tube was measured
using a digital balance and recorded in grams.
