What is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration ([magenta phenolphthalein]/[colorless phenolphthalein]) at a pH of 10.9?
Answers: 3
![\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}=31.62](/tpl/images/0513/8191/a145e.png)
![pH=pKa+\log\frac{[base]}{[acid]}](/tpl/images/0513/8191/949fe.png)
![10.9=9.40+\log\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}](/tpl/images/0513/8191/71cc8.png)
