Determine Solubility

Lab Summary

Use a pH sensor and drop counter to determine the solubility product of an ionic compound through titration and calculations.

Theory

Students demonstrate a method of determining the solubility product of an ionic compound.

Method

Students will gain experience conducting the following procedures:

  • Through titration and calculations, determine the solubility product of calcium hydroxide.
