In today's experiment, bromocresol indicator is used. It's molar mass is 698.0 g/mol. The stock solution contains 80.0 mg/L. If 10.0 mL of the stock indicator solution is added to a 50.0 mL volumetric flask and diluted to the mark with 0.4 M HCl solution, what is the micromolar (uM) concentration of the diluted indicator solution and what color is it ?
