Chemvue Labs for College Chemistry
These college-level General Chemistry lab activities are designed to work with Chemvue software, and can be edited to suit your students' needs. Teacher guides and student handouts are included for each investigation. Student handouts include background information, procedural instructions, questions that assist with data analysis and concept reinforcement, and guidance for lab reports. Each investigation is tightly integrated with our innovative software, sensors, and equipment.
Grade Level: College
Subject: Chemistry
Activities
01) Physical and Chemical Changes
Students use Wireless sensors (pH, conductivity, temperature, and pressure) with Chemvue software to characterize changes in matter as either physical or chemical and develop models of particle interactions.
02) Stoichiometry: Mole Relationships in Reactions
Students use a Wireless Conductivity Sensor and Chemvue software to determine the ideal ratio between silver nitrate and an unknown reactant.
03) Enthalpy of Change
Students use a Wireless Temperature Sensor, a calorimeter, and Chemvue software to calculate enthalpy and track the flow of energy into or out of a system undergoing either physical or chemical change.
04) Boyle's Law: The Gas Pressure-Volume Relationship
Students use a Wireless pressure sensor and Chemvue software to measure how the pressure of a fixed amount of gas responds when its volume is changed, and analyze the data to derive Boyle's law.
05) Kinetics: Reaction Order and Rate Constant
Students use a Wireless Pressure Sensor with included accessories and Chemvue software to determine the overall order and rate constant of a decomposition reaction.
06) Nernst Equation: Concentration versus Cell Potential
Students use a Wireless voltage sensor, Chemvue software, and Nernst equation calculations to compare measured Zn-Cu cell voltage against predicted values at standard and non-standard electrolyte concentrations.
