Caustic soda is a whitish solid, sold in pellets, flakes, and granular form.it is highly soluble in water, with a lower solubility in ethanol and methanol, but is insoluble in ether and other non-polar solvents.
Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction in which a large amount of heat is liberated, posing a threat to safety through the possibility of splashing. The resulting solution is usually colourless and odorless with slippery feeling upon contact in common with other alkalis.
Unlike sodium hydroxide, the hydroxides of most transition metals are insoluble, and therefore sodium hydroxide can be used to precipitate transition metal hydroxides.Zinc and lead salts dissolve in excess sodium hydroxide to give a clear solution of Na2ZnO2 or Na2PbO2.
Sodium hydroxide flakes can be used for Alumina production, Soap production, oil drilling, fuel production, pulp manufacturing for producing paper, biodiesel, aluminium etching, cleaning agent, leaded glass Window restoration, paint stripper, tissue digestion, food preparation, domestic uses and chemical analysis.
