Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a stainless steel temperature sensor to derive the enthalpy change of a reaction.
Students use Hess’s Law to calculate the enthalpy change of a reaction between ammonia and hydrochloric acid in aqueous solution.
Students gain experience conducting the following procedures:
Polystyrene cup, 8 oz.
Graduated cylinder, 50-mL or 100-mL
2.00 M Sodium hydroxide (NaOH) - 50 mL
2.00 M Hydrochloric acid (HCl) - 50 mL
2.00 M Ammonium chloride (NH4Cl) - 50 mL
2.00 M Ammonia (NH3) - 50 mL
This experiment may require software and an interface for data collection.
