What is the ratio of the magenta phenolphthalein concentration to the colorless phenolphthalein concentration ([magenta phenolph
lilavasa [31]

Answer:

\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}=31.62

Explanation:

Considering the Henderson- Hasselbalch equation for the calculation of the pH of the buffer solution as:

pH=pKa+\log\frac{[base]}{[acid]}

Where Ka is the dissociation constant of the acid.

pKa of phenolphthalein = 9.40

pH = 10.9

So,

10.9=9.40+\log\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}

\frac{[magenta\ phenolphthalein]}{[colorless\ phenolphthalein]}=31.62
