  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. Hydroxide - Wikipedia

    en.wikipedia.org/wiki/Hydroxide

    Hydroxide is a diatomic anion with chemical formula OH −. It consists of an oxygen and hydrogen atom held together by a single covalent bond, and carries a negative electric charge. It is an important but usually minor constituent of water. It functions as a base, a ligand, a nucleophile, and a catalyst.

  5. Sodium sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_sulfate

    Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na 2 SO 4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product.

  6. Hydrotalcite - Wikipedia

    en.wikipedia.org/wiki/Hydrotalcite

    Hydrotalcite, or formerly also völknerite, [6] is a layered double hydroxide (LDH) of general formula Mg. 6Al. 2CO. 3(OH) 16 ·4 H. 2O, whose name is derived from its resemblance with talc and its high water content. Multiple structures containing loosely bound carbonate ions exist.

    Salt (chemistry) The crystal structure of sodium chloride, NaCl, a typical salt. The purple spheres represent sodium cations, Na +, and the green spheres represent chloride anions, Cl −. The yellow stipples show the electrostatic forces. In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively ...

  8. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    Blue bottle reaction video. The blue bottle experiment is a color-changing redox chemical reaction. An aqueous solution containing glucose, sodium hydroxide, methylene blue is prepared in a closed bottle containing some air. Upon standing, it spontaneously turns from blue to colorless due to reduction of methylene blue by the alkaline glucose ...

  9. Humic substance - Wikipedia

    en.wikipedia.org/wiki/Humic_substance

    Humic and fulvic acids are extracted from soil and other solid phase sources into a strongly basic aqueous solution of sodium hydroxide or potassium hydroxide. Humic acids are precipitated from this solution by adjusting the pH to 1 with hydrochloric acid. The alcohol-soluble portion of humic fraction is, in general, named ulmic acid.
