Featured in PASCO’s Chemistry through Inquiry Teacher Guide
Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.
Test the law of conservation of matter for both physical and chemical changes by finding the mass of the reactants before the chemicals are reacted and the mass of the products after the reaction has occurred.
In this investigation, students test the law of conservation of matter for both physical and chemical changes.
Students conduct the following procedures:
Test tube, 15-mm × 100-mm - 2
Plastic soda bottle (with cap) - 500-mL
Sodium nitrate - 5 g
0.1 M Sodium sulfate - 5 mL
0.1 M Strontium chloride - 5 mL
Sodium bicarbonate - 8 g
5% Acetic acid - 30 mL
Distilled (deionized) water - 10 mL
This experiment may require software and an interface for data collection.
