a)  Draw the predominant chemical structure of Bromophenol Blue that exists under the pH

conditions of ammonium hydroxide (pH= 10). Under the structure, indicate its color.

b) Give a balanced chemical equation to represent the reaction that occurred when the TLC plate with Bromophenol Blue was immersed in 1 M HCl (pH less than 1). Under each dye structure, indicate whether it is an acid or a base, and its color.
