meaning of caustic soda?

Answer 1

(m)

sodium hydroxide: a strongly alkaline caustic used in manufacturing soap and paper and aluminum and various sodium compounds

Answer 2

Sodium hydroxide (NaOH), also known as lye or caustic soda, is a caustic metallic base. An alkali, caustic soda is widely used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents. Pure sodium hydroxide is a white solid, available in pellets, flakes, granules, and also 50% saturated solution. It is deliquescent and also 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. It is insoluble in ether and other non-polar solvents. A sodium hydroxide solution will leave a yellow stain on fabric and paper.
Sodium hydroxide is completely ionic, containing sodium ions and hydroxide ions. The hydroxide ion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts, e.g., with hydrochloric acid, sodium chloride is formed.

Solutions containing high concentrations of sodium hydroxide may cause chemical burns, permanent injury or scarring, and blindness.
Solvation of sodium hydroxide is highly exothermic, and the resulting heat may cause heat burns or ignite flamables.

Answer 3

Those men in question gang raped a 16 year old girl with the mental age of an 8 year old, then tried to destroy the evidence by pouring caustic soda over her. I would say that the should receive the maximum sentence which is life. I think if this is not a case for imposing a life sentence, then I don't know what is. If it were up to me, I keep them in solitary confinement for the rest of their lives, with NO form of entertainment, and no way of committing suicide, I also think they should have caustic soda poured into their eyes and genitals. Oh, and their imprisonment/punishment should all be filmed big brother style for our entertainment and as an educational tool. I'd call it " the punishment of subhuman scum"

Answer 4

caustic soda is sodium hydroxide

sodium hydroxide, chemical compound, NaOH, a white crystalline substance that readily absorbs carbon dioxide and moisture from the air. It is very soluble in water, alcohol, and glycerin. It is a caustic and a strong base (see acids and bases). Commonly known as caustic soda, lye, or sodium hydrate, it is available commercially in various solid forms, e.g., pellets, sticks, or chips, and in water solutions of various concentrations; both solid and liquid forms vary in purity. The major use of sodium hydroxide is as a chemical and in the manufacture of other chemicals; because it is inexpensive, it is widely used wherever a strong base is needed. It is also used in producing rayon and other textiles, in making paper, in etching aluminum, in making soaps and detergents, and in a wide variety of other uses. The principal method for its manufacture is electrolytic dissociation of sodium chloride; chlorine gas is a coproduct. Small amounts of sodium hydroxide are produced by the soda-lime process in which a concentrated solution of sodium carbonate (soda) is reacted with calcium hydroxide (slaked lime); calcium carbonate precipitates, leaving a sodium hydroxide solution.

Answer 5

Caustic soda is sodium hydroxide, a strong base or alkali.

Answer 6

from the Greek, caustics, meaning having the capability of severely burning or being corrosive or destroying to living tissue.Usually an alkali that destroys living tissue. Ex: silver nitrate, nitric acid, potassium hydroxide

Answer 7

caustic soda is used in food-manufacturing to dissolve the protein left behind. do NOT get it on your hands - it will dissolve your skin right quick.
