Lactic acid, C3H6O3 occurs in sour milk as a result on metabolism of certain bacteria.. What is the pH of a solution of 156 mg of lactic acid in 250 mL water? The Ka of lactic acid is 1.4 x 10-4. This problem is broken into steps over the next couple of problems. part 1. What is the initial concentration of lactic acid? part 2. What is the value of H3O+ concentration? part 3. What is the pH?

4. (10 pts) Lactic acid C3H603 is found in sour milk where it is produced by the action of lactobacilli in lactose or the sugar in milk. The pH of a 0.045 M solution of lactic acid was determined using a pH probe and found to be 2.63. a. Calculate the equilibrium constant for this acid. b. Had you not been given the pH of the acid and you had to measure it yourself, how would the method in part...

find the term isosbestic point.? [a. Explain why the isobestic point would be a poor choice of wavelength for determiningpKa? 5. Phenolphthalein is an indicator often used for weak acid-strong base titrations. The acid form of phenolphthalein is colorless and the base form is pink. Do you think the pKa of phenolphthalein would be determined using the same the method from this experiment to find the pKa for bromothymol blue? Explain why or why not? I dont need the answer...
