The experimental value of Kf depend on the amount of benzoic acid used. Source of error include the dissociation of Benzoic acid in water which allow formation of H+ and C6H5COOinstead of just C6H5COOH which directly affects the freezing point of TBOH solution.
I'm having a lot of trouble writing an abstract for this as well as answering some of the discussion questions.
The discussion questions are as follows with what I have put for them so far.
TBOH has a high affinity for water absorption due to its structure and water getting into the TBOH solution would result in false lows. Colligative properties define that the more particles in a solution the greater effect they have on the solution. For this experiment this applies to a depression of the freezing point and how it will lower significantly more with more ions dissolved in it.
