Product Description

As a former chemistry teacher (29 years), this was one of my favorite labs. Students had to think through the whole process and use their classroom knowledge to calculate the data table. I have provided a pre-lab data table with a key to use if you decide to discuss the data table before the lab. Some years, I would allow the students to complete the lab without explanation first. This really made the students THINK. After completing the lab, I would then go over the pre-lab data table and answer any questions the students had. I have also included a data table for an exit slip with a key.

Students will follow basic lab safety rules to heat potassium chlorate. They will determine the mass of oxygen produced and determine the percent yield for their data. They will use the balanced equation and complete mass-mass stoichiometry problem to calculate the percent yield for their data.

This lab uses lab skills as well as many chemistry concepts. Hope you and your students enjoy!
