Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide) Lye is a hydroxide, either sodium hydroxide or potassium hydroxide. The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH). In ...
Because of the use of caustic soda, and the very high pH of the dye bath in the dyeing process, wool cannot be dyed using vat dyestuffs. This is because wool is soluble in caustic soda solutions. Instead, it is possible to dye wool at room temperatures with indigo (vat blue 1) and other low substantive vat dyes using soda ash as the alkali ...
Chemical pulping involves dissolving lignin in order to extract the cellulose from the wood fiber. The different processes of chemical pulping include the Kraft process, which uses caustic soda and sodium sulfide and is the most common; alternatively, the use of sulfurous acid is known as the sulfite process, the neutral sulfite semichemical is treated as a third process separate from sulfite ...
Caustic most commonly refers to: Causticity, the property of being able to corrode organic tissue. Sodium hydroxide, sometimes called caustic soda; Potassium hydroxide, sometimes called caustic potash; Calcium oxide, sometimes called caustic lime; Caustic may also refer to: Caustic (band), an American industrial/powernoise band
Sodium bicarbonate, baking soda; Sodium hydroxide, caustic soda; Sodium oxide, an alkali metal oxide; Soda glass, a common glass made with sodium carbonate or sodium oxide; Soda lake, an alternate generic name for a salt lake, with high concentration of sodium carbonates; Soda lime, a mixture of sodium, calcium, and potassium hydroxides
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
It is a feedstock in the production of caustic soda and chlorine. These are used in the manufacture of PVC, paper pulp and many other inorganic and organic compounds. Salt is used as a flux in the production of aluminium. For this purpose, a layer of melted salt floats on top of the molten metal and removes iron and other metal contaminants.
