  2. Disodium hydrogen arsenate - Wikipedia

    en.wikipedia.org/wiki/Disodium_hydrogen_arsenate

    Disodium hydrogen arsenate is highly toxic. The salt is the conjugate base of arsenic acid. It is a white, water-soluble solid. [1] Being a diprotic acid, its acid-base properties is described by two equilibria: H 2 AsO − 4 + H 2 O ⇌ HAsO 2− 4 + H 3 O + (pK a2 = 6.94) HAsO 2− 4 + H 2 O ⇌ AsO 3− 4 + H 3 O + (pK a3 = 11.5)

    The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.

    Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...

  5. Selenous acid - Wikipedia

    en.wikipedia.org/wiki/Selenous_acid

    Selenous acid is analogous to sulfurous acid, but it is more readily isolated. Selenous acid is easily formed upon the addition of selenium dioxide to water. As a crystalline solid, the compound can be seen as pyramidal molecules that are interconnected with hydrogen bonds. In solution it is a diprotic acid: [3] H 2 SeO 3 ⇌ H + + HSeO − 3 ...

    en.wikipedia.org/wiki/IUPAC_polymer_nomenclature

    A polymer is a substance composed of macromolecules. The latter usually have a range of molar masses (unit g mol −1), the distributions of which are indicated by dispersity (Đ). It is defined as the ratio of the mass-average molar mass (M m) to the number-average molar mass (M n) i.e. Đ = M m /M n. [4]

  9. Squaric acid - Wikipedia

    en.wikipedia.org/wiki/Squaric_acid

    Squaric acid, also called quadratic acid because its four carbon atoms approximately form a square, is a diprotic organic acid with the chemical formula C 4 O 2 (OH) 2. [4]The conjugate base of squaric acid is the hydrogensquarate anion HC 4 O − 4; and the conjugate base of the hydrogensquarate anion is the divalent squarate anion C 4 O 2− 4.
