Question

A solution is prepared containing 8.00 g of trichloroacetic acid, CCI_3COOH, in 92.0 g of water. This solution is also 0.509 M. a) calculate the mol fraction of trichloroacetic acid in the solution. b) calculate the freezing point of the solution (assuming the CCI_3COOH does not dissociate into ions.) c) the experimental freezing point of this solution is found to be -1.69 degreeC. Is trichloroacetic acid a strong, weak or nonelectrolyte in water? Explain. d) Identify the chemical specie(s) in an aqueous solution of trichloroacetic acid. (NOTE: you need not include water, just the specie(s) associated with trichloroacetic acid.) Which is/are present in the highest concentration? Explain. c) Calculate the density of this solution.

Explanation / Answer

4.A) Trichloro acetic acid Mole fraction is 0.009496
