Title: Dilution of a solution of phenol with trichloroacetic acid
Post by: Magic_Doctor on January 30, 2018, 04:50:00 PM

Hello,

I would like to solve the following problem:

I have 20 mL of 30% trichloroacetic acid (TCA) in aqueous solution.
How much of a solution of phenol in aqueous solution concentrated to 88% will I have to pour into the TCA solution to reduce its concentration to 10%?
What will be the concentration of TCA?

I would simply like to know if there is or not one or more formulas that can solve this problem.

Hi,

I found it.

Phenol (88%) --> 2.72 mL
TCA (30%) --> 26.59%
