Prepare Oxygen from Hydrogen Peroxide by ctremblaylcsd150 is a document available to read on EtoBox.
This experiment produces oxygen gas from hydrogen peroxide and potassium iodide. The gas is collected in an inverted test tube submerged in water. Properties of oxygen are then observed, including its smell when sniffed and its ability to relight a glowing splint. The experiment also compares the solubility of oxygen and ammonia in water by bubbling each gas into a flask of water. Students are asked to summarize their observations and describe how the results could help identify an unknown gas as oxygen or
