pH ^ of an acid buffer is given by

Options

  1. ApH = pK _ a + [ Salt ] [ Acid ]
  2. BpH = pK _ a - [ Salt ] [ Acid ]
  3. CpH = K _ a + [ Salt ] [ Acid ]
  4. DNone of the above

Correct answer

A. pH = pK _ a + [ Salt ] [ Acid ]

Step-by-step solution

pH of an acid buffer is given by Henderson equation. pH =- K_a+ [ Salt ] [ Acid ] or pH = p K_a+ [ Salt ] [ Acid ]
