At what temperature should conductivity measurements ideally be taken?

Conductivity measurements are ideally taken at 25 degrees Celsius because this temperature is considered the standard reference point for many analytical methods, including the determination of the electrical conductivity of aqueous solutions. At this temperature, the effects of temperature on ionic mobility are well-characterized, allowing for a more accurate comparison of results from different samples.

Conductivity can significantly change with temperature; as temperature increases, the conductivity of most aqueous solutions tends to increase due to enhanced ionic mobility. Thus, by standardizing measurements at 25 degrees Celsius, laboratories can ensure consistency and reliability in their data, making comparison over time or between different testing locations much easier. This is a key practice in laboratory analysis to maintain quality control and data accuracy.
