Three buffers are made by combining a 1M solution of acetic acid and a 1M solution of sodium acetate in the ratios shown in the table below. Which of these statements is true regarding the prepared buffers? (Ka= 1.7x10-5) 1M acetic acid 1M sodium acetate Buffer 1 10 ml 90 ml Buffer 2 50 ml 50 ml Buffer 3 90 ml 10 ml pH of buffer 1 > pH of buffer 2 = pH of buffer 3 pH of buffer 1 > pH of buffer 2 > pH of buffer 3 pH of buffer 1 < pH of buffer 2 < pH of buffer 3 pH of buffer 1 = pH of buffer 2 > pH of buffer 3 pH of buffer 1= pH of buffer 2 = pH of buffer 3
