WebPhysical Properties of Sodium Hydroxide. Sodium Hydroxide in its pure form is a white crystalline solid. It is odourless. It is soluble in water, glycerol and ethanol. When solid sodium hydroxide is mixed with water it results in a highly exothermic reaction. Has a higher viscosity than water about 78 mPas. It can form several hydrates.
