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:
