[To all users]

• Confirm the law of conservation of mass using the reaction between Hydrochloric acid and Sodium Hydrogen Carbonate.
• Easy to Compare substance’s mass in the reactor before and after the reaction between Hydrochloric acid and Sodium Hydrogen Carbonate.
• The special rubber ring of the reactor can completely seal the gas produced by the reaction.

[To teachers]

• Thought, in general, the confirmation of the law of conservation of mass is difficult experiments with chemical reactions, if you use this reactor, the confirmation (experiment) becomes easy.
• Easy to measure the mass.
• The instructor or teacher can let learners experiment with safety due to its safe reactor and its easy ways.

[To students]

• Learners can experiment with the law of conservation of mass by themselves and confirm the law according to their results.
