2. Three buffers are made by combining a 1 M solution of acetic acid with a 1 M solution of sodium acetate in theratios shown below.Buffer 1:Buffer 2:Buffer 3:1 M acetic acid10 mL50 mL90 mL(i)(ii)(iii)1 M sodium acetate90 mL50 mL10 mLa. Which of these statements is true of the resulting buffers?pH of buffer 1 < pH of buffer 2 < pH of buffer 3pH of buffer 1 = pH of buffer 2 = pH of buffer 3pH of buffer 1 > pH of buffer 2 > pH of buffer 3b. Which solution resists changes in pH most effectively?

This question is based on pH calculation of buffer solution and buffer capacity.
