Stoichiometry in Solutions

Students use conductometric titration and particle modeling to study the stoichiometry of acid-base titration.

Conductometric titration is used to demonstrate that as neutralization occurs in an acid-base titration, the loss of free ions in solution correlates to a reduction in conductivity. This lab also demonstrates that the neutralization reaction is associated with a change in the temperature of the system. All changes are tracked through the equivalence point of the reaction.

Featured Equipment

Wireless Drop Counter

Wireless Drop Counter

Use the new Wireless Drop Counter for more efficient and accurate titration data. Conducting a titration has never been easier!

Wireless Conductivity Sensor

Wireless Conductivity Sensor

This waterproof sensor connects via Bluetooth® to measure both conductivity (ionic content in solution) and total dissolved solids.

Temperature Sensor

Wireless Temperature Sensor

The Wireless Temperature Sensor is a general-purpose sensor found in many science labs. With a rugged, waterproof design, and long-lasting battery, students can spend more time collecting data and less time dealing with equipment.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
