A buffer is made by adding 0.120 mol of lactic acid, (CH3COHCOOH - monoprotic), HC3H5O3, and 0.100 mol of sodium lactate, NaC3H5O3 to enough water to make 1.00 L of solution. The pH of the buffer was calculated in question # 6. <-- pH = 3.77
A) Calculate the pH of the solution after 0.001 mol of NaOH is added. Ka (lactic acid) = 1.4 x 10-4. Assume no volume change.
B) Calculate the change in pH if 0.001 mol of NaOH is added to 1.00 L of pure water.
