2. Sodium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Sodium_hydroxide

   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 ...

3. Base (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Base_(chemistry)

   Sodium hydroxide. When one molecule of a base via complete ionization produces one hydroxide ion, the base is said to be a monoacidic or monoprotic base. Examples of monoacidic bases are: Sodium hydroxide, potassium hydroxide, silver hydroxide, ammonium hydroxide, etc.

4. Neutralization (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Neutralization_(chemistry)

   For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be written as H + + OH − → H 2 O. For example, in the reaction between hydrochloric acid and sodium hydroxide the sodium and chloride ions, Na + and Cl − take ...

5. Lye - Wikipedia

   en.wikipedia.org/wiki/Lye

   A lye refers to sodium hydroxide and 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 order to distinguish between the two, sodium hydroxide may be referred to as soda lye while ...

6. Basic oxide - Wikipedia

   en.wikipedia.org/wiki/Basic_oxide

   All oxides of group 1 & 2 elements are basic (except BeO), they react with water to form a base: [2] Lithium oxide reacts with water to produce lithium hydroxide: Li 2 O + H 2 O → 2 LiOH; Sodium oxide reacts with water to produce sodium hydroxide: Na 2 O + H 2 O → 2 NaOH; Potassium oxide reacts with water to produce potassium hydroxide: K 2 ...

7. Weak base - Wikipedia

   en.wikipedia.org/wiki/Weak_base

   An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. [4] The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base. [5]

8. Free base - Wikipedia

   en.wikipedia.org/wiki/Free_base

   The free base form of cocaine is prepared from cocaine hydrochloride by extracting the cocaine with an alkaline solution (sodium hydroxide or ammonia) and adding a non-polar solvent such as diethyl ether or benzene. The mixture separates into two layers, the top solvent layer containing the dissolved cocaine.

9. Acid–base extraction - Wikipedia

   en.wikipedia.org/wiki/Acid–base_extraction

   By rinsing the crude product mixture with a weak base (e.g. sodium bicarbonate), the carboxylic acid and alcohol will be washed away with the aqueous layer, leaving purified ester in the organic layer. [14] The choice of base used for extraction is critical, as a strong base (e.g. sodium hydroxide) will hydrolyze the ester.
