DEMO 3-1 A: THE SYNTHESIS OF OXYGEN Name: Date: Block: PURPOSE: To decompose hydrogen peroxide by adding a catalyst and to observe a positive test for oxygen gas. MATERIALS: Refer to p. 77 of BC Science 9 PROCEDURE: Refer to p. 77 of BC Science 9 DATA/OBSERVATIONS/RESULTS: Title: Observations of the decomposition of hydrogen peroxide and the positive test for oxygen Procedure Step Observations Evidence of a chemical reaction. Glowing splint reacting with oxygen gas. CONCLUSION 1. a) What happens to a glowing splint when it is placed in pure oxygen? b) Do some research to explain your observations. (What are characteristics of oxygen that may result in these observations?)
