Sodium hydroxide (NaOH),also known as lye and caustic soda,is a
caustic metallic base.It is used in many industries,mostly as a strong
chemical base in the manufacture of pulp and paper,textiles,drinking
water,soaps and detergents and as a drain cleaner.
Pure sodium hydroxide is a white solid available in
pellets,flakes,granules,and as a 50% saturated solution.It is
hygroscopic and readily absorbs carbon dioxide from the air,so it
should be stored in an airtight container.It is very soluble in water with
liberation of heat.
It also dissolves in ethanol and methanol,though it exhibits lower
solubility in these solvents than does potassium hydroxide.Molten
sodium hydroxide is also a strong base,but the high temperature
required limits applications.It is insoluble in ether and other non-polar
solvents.A sodium hydroxide solution will leave a yellow stain on
fabric and paper.
Micro Pearls Characteristics:Its appearance is that of a white
bead/pearl with less metal purity.It is also called caustic soda
pearls,caustic soda prills,or caustic soda pellets,etc.Caustic soda
pearls usually dissolve 2 or 3 times faster than flakes.
