Question
What is the concentration of saturated KCl?
Answer

The concentration of saturated KCl depends on the temperature-dependent solubility.

In our bottles, there are always crystals of KCl in excess to ensure saturation.

KCl solubility at 20°C: 0,340 g·cm-3 in water = 340 g/l = 4.56 mol/l (Saturated KCl at 20°C)

KCl solubility at 30°C: 0,374 g·cm-3 in water = 374 g/l = 5.02 mol/l (Saturated KCl at 30°C)
