Densities of Aqueous Solutions of Organic Acids
Changes in density of aqueous solutions with changes in concentration at 20°C. Density of acetic acid, citric acid, formic acid, D-lactic acid, oxalic acid and trichloroacetic acid 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.
