12. Lactic acid (HC3H5O3) is present in sour milk It is a monoprotic acid. In a 0.100 M solution of lactic acid, the pH is 2.44 at 25°C. Calculate Ka and pKa for lactic acid at that temperature. (10)
Lactic acid CH3CHOHCOOH is found in sour milk, in sauerkraut, and in muscles after activity. Lactic acid is a weak monoprotic acid in aqueous solution, with a Ka = 1.4x10^-4 at 25 degree. 2.15g of sodium hydroxide was added to 8.00x10^2 mL of an aqueous solution containing 0.100mol/L lactic acid. a) Determine the pH of the resulting solution b)determine the concentrations of all neutral acid ionic species (other than water) present in the resulting solution
A 0.10 M solution of a weak monoprotic acid was found to have a pH of 1.92. Calculate the percent dissociation and pKa for this acid.
Lactic acid, HC3H5O3, is a substance found in sour milk products such as yogurt, and is produced naturally by fermentation in body cells during normal metabolism and exercise The Ka for lactic acid is 38 x 10-4. Its sodium salt, sodium lactate, NaC3H5O3, is used in foods as a preservative and acidity regulator. It is also used in shampoo products as an effective humectant and moisturizer. Determine the pH of a solution prepared by adding 4.5 grams of sodium lactate...
