Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Mole Relationship in Reaction
Use a conductivity sensor to determine the stoichiometric coefficients of the reactants of a chemical reaction.
Students determine the stoichiometric coefficients of the reactants of a chemical reaction using conductivity.
Students gain experience conducting the following procedures:
- Using conductivity to monitor a reaction.
- Determining the stoichiometric ratio of the reactants.
