I don't remember the question exactly but it is roughly as follows: You have 225mL of .0078M hydrobromic acid in a buret with a little bit of phenolphthalein in it. In the flask, you have 49.85mL of .0165M potassium hydroxide. Upon the entirety of the hydrobromic acid and potassium hydroxide being mixed, what color does the solution become?

What I'm wonder is, does it become pink due to the phenolphthalein, or another color? The pH of the mixed solution is 2.47, I believe (if my math is correct)
