1516L - Solubility of a Solid in Water

Details of this experiment are found in the handout here. You will use the MicroLab analysis equipment in order to accurately measure the temperature at which crystallization occurs for 5 different concentrations of queous KNO3 solution.

Instructions for how to calibrate the MicroLab thermocouple are found here.

Instructions for how to construct a graph using the MicroLab software are found here.

MicroLab Analysis Box

The front of the box has a series of ports for different probes (many of which you will use in 1516L); you insert the new thermocouple (shown below) and calibrate as usual:

The Experiment Setup

Once you have the thermocouple calibrated, set up the experiment as shown below:

When the experiment is complete, dispose of any waste, return the thermocouple to the front bench and clean up the balance room and your work area as needed.
