why we are used 4,7,9,2 buffers for the ph calibration
Answer Posted / arash babakhanian
pH is determined from this equation in the pH meter
pH = [(Eobs-K)/0.059]n
Eobs= observed potential
K= constant paramere
0.059=slope
constant parameters k and 0.059 should be calibrated. In
fact two acidic buffers and two alkalic buffers are used to
fix slope and K constant . In this case, the relation
between Eobs and pH is analyticaly change
