    en.wikipedia.org/wiki/Sodium_pyrosulfate

    Sodium pyrosulfate is an inorganic compound with the chemical formula of Na 2 S 2 O 7. [1] It is a colorless salt. [ 3 ] It hydrolyses in water to form sodium bisulfate with a chemical formula of NaHSO4 which has a pH of around 1.

  4. 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.

    For example, 15-crown-5 has a high affinity for sodium because the cavity size of 15-crown-5 is 1.7–2.2 Å, which is enough to fit the sodium ion (1.9 Å). [ 19 ] [ 20 ] Cryptands, like crown ethers and other ionophores , also have a high affinity for the sodium ion; derivatives of the alkalide Na − are obtainable [ 21 ] by the addition of ...

    The Birnbaum–Saunders distribution, also known as the fatigue life distribution, is a probability distribution used extensively in reliability applications to model failure times. The chi distribution. The noncentral chi distribution; The chi-squared distribution, which is the sum of the squares of n independent Gaussian random variables.

  8. Bisulfite - Wikipedia

    en.wikipedia.org/wiki/Bisulfite

    Sodium bisulfite is a decoloration agent in purification procedures because it reduces strongly coloured oxidizing agents, conjugated alkenes and carbonyl compounds. Bisulfite is also the key ingredient in the Bucherer reaction. In this reaction an aromatic hydroxyl group is converted to the corresponding amine group. This is a reversible reaction.

  9. Sodium thiocyanate - Wikipedia

    en.wikipedia.org/wiki/Sodium_thiocyanate

    Sodium thiocyanate (sometimes called sodium sulphocyanide) is the chemical compound with the formula NaSCN. This colorless deliquescent salt is one of the main sources of the thiocyanate anion . As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals . [ 2 ]
