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....

If you could answer 1 and 2 please. Thanks!
Introduction One of the best ways to make aromatic amines is to exploit a rearrangement reaction that breaks a C-C bond. To achieve the rearrangement, you need to make an acyl nitrene intermediate (or suitable derivative). There are a variety of these processes: the Curtius and Schmidt rearrangements access the nitrenes from acyl azides, but these can be explosive, so aren't ideal for an undergraduate lab. The other method is to...
