Students examine equilibrium and buffer solutions in a biological setting.
LAB
In this exercise, students graph the titration curve of an unknown acid and base to determine their pKa’s and concentrations.
LAB
Textbook-style weak acid and base problems that can be checked using the Virtual Lab.
LAB
Use the Virtual Laboratory to standardize an unknown NaOH solution (approximately 0.2M) to four significant figures via titration with 25.00 mL of a KHP standard solution.
LAB
Use the virtual lab to determine the pKa of a protein then create a buffer solution with a specific concentration ratio of the protein in its protonated/ unprotonated form.

This activity was created as an accompaniment to an in-class demonstration of the method of successive dilutions using HCl, NaOH, a pH meter, and universal indicator solution. After the demonstration, students were assigned the Virtual Lab activity to complete in class.

LAB
GIven the solubility of CuCl at 2 different temperatures, predict its solubility at a third temperature. Then test your prediction by creating the solution in the virtual lab.
