Assume that you have an unknown solution in a test tube. When you add phenol red to the test tube, it appears pale pink. It takes 30 drops of hydrochloric acid (HCl) for the phenol red to turn yellow. Based on your experience in the Antacids as Buffers simulation, this is an indication that the solution in the tube is
