Densities of Aqueous Solutions of Inorganic Potassium Salts
Changes in density of aqueous solutions with changes in concentration at 20°C. Density of potassium salts in water is plotted as function of wt%, mol/kg water and mol/l solution.
Be aware of the concentration units in the figures:
wt%: Mass of solute/total mass of solution ×100%
mol/kg: Molality = moles of solute/kg of water
mol/liter: Molarity = moles of solute/liter of solution
Values are tabulated below the figures.
See also density of aqueous solutions of inorganic chlorides, inorganic sodium salts, some other inorganic substances, organic acids and organic substances as sugars and alcohols.
