Three buffers are made by combining a 1 M solution of citric acid with a 1 M solution of sodium citrate in the ratios shown below: 1 M Citric Acid 1 M Sodium Citrate Buffer 1: 90 mL 10 mL Buffer 2: 50 mL 50 mL Buffer 3: 10 mL 90 mL Which of these statements is true of the resulting buffers? Question 37 options: A) pH of buffer 1 < pH of buffer 2 < pH of buffer 3. B) pH of buffer 1 = pH of buffer 2 = pH of buffer 3. C) pH of buffer 1 > pH of buffer 2 > pH of buffer 3. D) The problem cannot be solved without knowing the value of pKa
