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...

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
