Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use an absolute pressure sensor and stainless steel temperature sensor to identify an unknown metal by applying the Ideal Gas Law.
Students identify an unknown metal by applying and relating the Ideal Gas Law, the three possible oxidation numbers of metals, and the periodic table of elements.
Students gain experience conducting the following procedures:
Graduated cylinder, 10-mL or 25-mL
Graduated cylinder, 250-mL
Erlenmeyer flask, 250-mL
Balance - 1 per class
Rubber stopper with one hole
3 M Hydrogen chloride (HCl) - 100 mL
Unknown metal, 0.2 g (use magnesium ribbon) - 3 pieces
Electrical tape - 1 roll
This experiment may require software and an interface for data collection.
