Question

 A buffer solution contains 0.10 mol of propionic acid (C2H5COOH, Ka = 1.3 X 10-5) and 0.13 mol of sodium

propionate (C2H5COONa) in 1.50 L of aqueous solution. A. What is the pH of this buffer? B. What is the pH of the buffer after the addition of .010 mol of NaOH? C. What is the pH of the buffer after the addition of .010 mol of HCl? 

Top Answer

A) pH of acidic buffer = pKa + log (salt / acid) Number of moles of C 2 H 5 COOH= 0.10 moles Number of moles of C 2 H 5 COONa... View the full answer
