1.
Potassium chloride
Grind potassium chloride (for conductivity measurement use) stipulated in JIS-K8121 in
an agate mortar to make it into a powder, heat it up to 500
C for approximately four hours,
and then leave it in a desiccator to cool.

C) potassium chloride standard solution preparation
Measure and put 0.744 g of potassium chloride into a 1000 mL flask and fill it with purified
water up to the gauge line. Put 100 mL of this solution into another 1000 mL flask and fill
it with purified water up to the gauge line.
