C. Analyzing an unknown base - optimizing a method: In this segment you will design your own method for analyzing an unknown base. In the solutions list there are several different concentrations of HCl to choose from. You can also try different sample volumes of the unknown base. Be sure to record these for each trial. Your goal is to find two different combinations of HCI...
