  2. Propionic acid - Wikipedia

    en.wikipedia.org/wiki/Propionic_acid

    The esters of propionic acid have fruit-like odors and are sometimes used as solvents or artificial flavorings. [15] In biogas plants, propionic acid is a common intermediate product, which is formed by fermentation with propionic acid bacteria. Its degradation in anaerobic environments (e.g. biogas plants) requires the activity of complex ...

  3. Deprotonation - Wikipedia

    en.wikipedia.org/wiki/Deprotonation

    Therefore, the side of the equation with water will be formed preferentially. If, for example, water, instead of hydroxide, was used to deprotonate the carboxylic acid, the equilibrium would not favor the formation of the carboxylate salt. This is because the conjugate acid, hydronium, has a pK a of -1.74, which is lower than the carboxylic ...

    The following compounds are liquid at room temperature and are completely miscible with water; ... nitric acid: 7697-37-2 H 2 O 2: hydrogen peroxide: 7722-84-1 HF:

  5. Acidogenesis - Wikipedia

    en.wikipedia.org/wiki/Acidogenesis

    Acetic acid is equally a co-metabolite of the organic substrates fermentation (sugars, glycerol, lactic acid, etc.) by diverse groups of microorganisms which produce different acids: Propionic bacteria (propionate + acetate); Clostridium (butyrate + acetate); Enterobacteria (acetate + lactate); and

  6. Grotthuss mechanism - Wikipedia

    en.wikipedia.org/wiki/Grotthuss_mechanism

    Protons tunnel across a series of hydrogen bonds between hydronium ions and water molecules.. The Grotthuss mechanism (also known as proton jumping) is a model for the process by which an 'excess' proton or proton defect diffuses through the hydrogen bond network of water molecules or other hydrogen-bonded liquids through the formation and concomitant cleavage of covalent bonds involving ...

  7. Protonation - Wikipedia

    en.wikipedia.org/wiki/Protonation

    In chemistry, protonation (or hydronation) is the adding of a proton (or hydron, or hydrogen cation), usually denoted by H +, to an atom, molecule, or ion, forming a conjugate acid. [1] (The complementary process, when a proton is removed from a Brønsted–Lowry acid, is deprotonation.) Some examples include The protonation of water by ...

  8. Miscibility - Wikipedia

    en.wikipedia.org/wiki/Miscibility

    Diesel fuel is immiscible in water.The bright rainbow pattern is the result of thin-film interference.. Miscibility (/ ˌ m ɪ s ɪ ˈ b ɪ l ɪ t i /) is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution).

  9. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    An example of this case would be the splitting of hydrochloric acid HCl in water. Since HCl is a strong acid (it splits up to a large extent), its conjugate base (Cl −) will be weak. Therefore, in this system, most H + will be hydronium ions H 3 O + instead of attached to Cl − anions and the conjugate bases will be weaker than water molecules.
