Homework Answers
I have solved part a and b but
I think there is some error in observed osmotic pressure as I have
varified my calculation twice please let me know if there is still
any error in my calculation.

5) A semi-permeable membrane is used to separate pyruvic acid from an aqueous solution of 0.1 mg/L pyruvic acid solution. a) Calculate the osmotic pressure expected in the solution, if pyruvic acid completely dissociates. b) Calculate the osmotic pressure expected in the solution if pyruvic acid does not dissociate. c) What is the pka of the solution if the observed osmotic pressure of the solution is 4920 Pa. (hint: Use the values from a and b to estimate the dissociation...
