Calculate the pH of an acetic acid solution in which [CH3COO - ] = 0.037 M and [CH3COOH] = 0.044 M. (pKa = 4.76) 4. You are conducting a biochemical experiment with an enzyme that has optimal activity at pH = 10.00. You decide to use carbonate (pKa1 = 6.38, pKa2 = 10.30) as the buffer to keep the pH stable throughout the enzymatic reaction. (Recall that the formula for carbonic acid is H2CO3.) You prepare a 0.5 M solution of carbonate buffer at pH = 10.00. Calculate the concentrations of the major carbonate species in your solution. 5. Calculate the pH of the buffer solution in which [H3PO4] = 0.038 M and [H2PO4 - ] = 0.046 M (pKa1 = 2.12, pKa2 = 7.21, pKa3 = 12.32). 6.
