Here's some information about the conductivity of 0.01 molal (m) potassium chloride (KCl) solutions at different temperatures:
25 °C: The conductivity of a 0.01 m KCl solution at 25 °C is 0.00140823 S/cm.
0–50 °C: The conductivity of a 0.01 m KCl solution has been measured over the temperature range of 0–50 °C in 5 degree intervals. The overall uncertainty over the entire temperature range is estimated to be 0.03%.
Temperature coefficient: The temperature coefficient for KCl solutions is about 2%/°C, but varies significantly with temperature and concentration.
At high temperatures (45 and 50 °C), small air bubbles can form in the chamber between electrodes, which can lead to higher resistance readings. To get rid of the bubbles, you can take the cell out and rotate it. However, this process can lead to a loss of water vapor, resulting in lower resistance readings.
