Preparation and Collection of Gases – Oxygen, Carbon Dioxide & Ammonia #csecchemistry #cxcchemistry

In this video, I explain how to prepare and collect three common gases: Oxygen (O₂) Carbon Dioxide (CO₂) Ammonia (NH₃) I cover: How each gas is prepared in the lab Their solubility in water Which drying agent is used How each gas is collected (upward or downward delivery, or over water) Great for students studying CSEC Chemistry or doing lab work!
