  2. 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 ...

  3. Saponification - Wikipedia

    en.wikipedia.org/wiki/Saponification

    The reaction of fatty acids with base is the other main method of saponification. In this case, the reaction involves neutralization of the carboxylic acid. The neutralization method is used to produce industrial soaps such as those derived from magnesium, the transition metals, and aluminium.

  4. Alkali hydroxide - Wikipedia

    en.wikipedia.org/wiki/Alkali_hydroxide

    Alkali hydroxides are formed in the reaction between alkali metals and water. A typical school demonstration demonstrates what happens when a piece of an alkali metal is introduced to a bowl of water. A vigorous reaction occurs, producing hydrogen gas and the specific alkali hydroxide. For example, if sodium is the alkali metal:

  5. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    Molecular models of the different molecules active in Piranha solution: peroxysulfuric acid (H 2 SO 5) and hydrogen peroxide (H 2 O 2). Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4) and hydrogen peroxide (H 2 O 2). The resulting mixture is used to clean organic residues off substrates, for example ...

  7. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2 Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO 2 , Na 3 AlO 3 , Na[Al(OH) 4 ] , Na 2 O·Al 2 ...

  8. Chemical drain cleaners - Wikipedia

    The corresponding reactions are shown below. Because the release of hydrogen gas is overall an exothermic reaction, the extra heat released helps to break down the greases, oils, etc. that form the clog. 1. Breakdown of aluminum oxide: Al 2 O 3 + 2NaOH + 3H 2 O → 2Na[Al(OH) 4] 2. Oxidation of aluminum metal: 2Al + 2NaOH + 6H 2 O → 2Na[Al(OH ...

  9. Sodium hydrosulfide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydrosulfide

    This compound is the product of the half-neutralization of hydrogen sulfide (H 2 S) with sodium hydroxide (NaOH). NaSH and sodium sulfide are used industrially, often for similar purposes. Solid NaSH is colorless. The solid has an odor of H 2 S owing to hydrolysis by atmospheric moisture.
