  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. Layered double hydroxides - Wikipedia

    en.wikipedia.org/wiki/Layered_double_hydroxides

    Size: 8.4 × 5.2 × 4.1 cm. Layered double hydroxides (LDH) are a class of ionic solids characterized by a layered structure with the generic layer sequence [AcB Z AcB] n, where c represents layers of metal cations, A and B are layers of hydroxide (OH−. ) anions, and Z are layers of other anions and neutral molecules (such as water). [1]

  4. Alkali soil - Wikipedia

    en.wikipedia.org/wiki/Alkali_soil

    Chemistry. Soil alkalinity is associated with the presence of sodium carbonate (Na 2 CO 3) or sodium bicarbonate (NaHCO 3) in the soil, [5] either as a result of natural weathering of the soil particles or brought in by irrigation and/or flood water. This salt is extremely soluble, when it undergoes hydration, it dissociates in:

  5. Precipitation (chemistry) - Wikipedia

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

    Precipitation (chemistry) In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [1][2] The solid formed is called the precipitate. [3] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant. [4]

  6. Saponification - Wikipedia

    en.wikipedia.org/wiki/Saponification

    Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1][2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate ...

  7. Friedel's salt - Wikipedia

    en.wikipedia.org/wiki/Friedel's_salt

    Kuzel's salt structure is composed of the perfect intercalation of the Friedel's salt structure and the monosulfoaluminate structure (the two end-members of the studied bi-anionic AFm compound). The structural properties of Kuzel's salt explain the absence of extended chloride to sulfate or sulfate to chloride substitution.

  8. Ion-exchange resin - Wikipedia

    en.wikipedia.org/wiki/Ion-exchange_resin

    Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.

  9. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq).
