Description
The Law of Conservation of Mass Apparatus Bottle, also known as a conservation of mass reaction bottle, is designed for classroom demonstrations where students compare the mass of a sealed reaction system before and after two chemicals are combined. This apparatus clearly supports the teaching of the Law of Conservation of Mass by allowing students to measure the mass of the bottle and contents before the reaction, then compare it with the mass after the reaction has taken place. The bottle is suitable for demonstrating the reaction between hydrochloric acid and sodium hydrogen carbonate, where gas is produced during the reaction. In a properly sealed setup, the total mass of the closed system can be compared before and after reaction.
The special rubber ring of the reactor is listed as helping to completely seal the gas produced by the reaction, supporting a clearer demonstration of mass conservation in a closed vessel. This Narika product is useful for school science laboratories, university teaching laboratories and chemistry classrooms requiring a practical, visual and easy-to-understand demonstration of chemical change and closed-system mass comparison. Users should confirm chemical concentration, reagent quantity, sealing method, balance readability, reaction procedure and safety requirements before use.
Use only under approved laboratory procedures. Hydrochloric acid should be handled with suitable PPE, and the bottle must not be overfilled, overheated, pressurised beyond its intended use or opened carelessly after reaction. This product is intended for laboratory or educational settings only and should be used under appropriate supervision. This item is supplied as the Law of Conservation of Mass experiment bottle only. Hydrochloric acid, sodium hydrogen carbonate, balance, weighing paper, droppers, PPE, worksheets and additional chemistry accessories are not included unless specified separately.
LabChoice Australia supplies Conservation of Mass Experiment Bottles and chemistry teaching apparatus for school science laboratories, university teaching laboratories and educational facilities requiring practical tools for chemical reaction and mass conservation demonstrations.
