131.Solving a chemistry problem

Product description

• Using the data from the previous problem, determine the distribution coefficient of salicylic acid between water and benzene.

Data from the previous problem:

• When distributing salicylic acid between water and benzene at 293 K, the following data were obtained:

C1 0.0363 0.0940 0.210

C2 0.0184 0.0977 0.329

Here C1 and C2 are the equilibrium acid concentrations (in mol/l) in the aqueous and benzene layers, respectively. Prove that the molecular state of salicylic acid in water and benzene is not the same.
