Concentrative Properties of Aqueous Solutions

Notes

• All data at 20 °C
• Mass %: mass of solute divided by mass of solution times 100 %
• m: moles of solute divided by kg of solvent
• ρ: mass density of solution
• n: index of refraction, relative to air, at a wavelength of 589 nm (sodium D line); the index of pure water at 20 °C is 1.3330
• Δ: freezing point depression relative to pure water
• η: Absolute (dynamic) viscosity in mPa s (equal to centipoise, cP); the viscosity of pure water at 20 °C is 1 .002 mPa s
