Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Enthalpy of Chemical Reaction
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:
- Carrying out and monitoring the temperature change of 3 reactions.
- Comparing the results of the enthalpy calculated from the heat of reaction to that calculated using Hess’s Law.
Sensors / Equipment Used:
Allows students to measure Temperature, pH/ISE/ORP, Absolute Pressure & Voltage in one sensor. For use with PASPORT Interfaces.
