Question- In the experiment, a point is made that the formation of the azo compound is a slow reaction but the rate is increased by raising the pH of the solution. Why is this necessary? In other words, how does the pH of the solution affect the reactivity of the N/N-dimethylaniline reagent?

Show all work, use additional paper if necessary.
