1.Temperature compensation

The pH range (0-14) is determined through the ion product of the water, which to a very small extent dissociates into H+ and OH– ions. [H+ ] [OH– ] = 10–14 = I (25°C) The ion product I is strongly dependent on temperature.

The temperature influences the pH measurement through four factors:

• Chemical equilibria are temperature dependent

• Temperature dependence of the slope (see Nernst equation below)

• Position of the isothermal intersection

• Differing response time of the electrode (caused by temperature changes).

 

Every measuring solution has a characteristic temperature and pH behaviour (temperature coefficient). In general you should assume that a
temperature change results in a pH change (see buffer/temperature
table below). The reason for this is the temperature dependent dissociation which causes a change in the H+.

 

 

Buffer/temperature table Example:

  20℃ 30℃
0.001 mol/ L HCI pH 3.00 pH 3.00
0.001 mol/ L NaOH pH 11.17 pH 10.83
phosphate buffer pH 7.43 pH 7.40
Tris buffer pH 7.84 pH 7.56
