  2. Calcium bisulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_bisulfite

    A calcium bisulfite liquor solution is used in the process of converting dihydroquercetin in tree bark pulp and then converting dihydroquercetin to a usable form: quercetin. Calcium bisulfite is not the optimum bisulfite compound for this reaction since the calcium ions can be removed from the calcium bisulfite solution during the reaction ...

  3. Bisulfite - Wikipedia

    en.wikipedia.org/wiki/Bisulfite

    In this technique, sodium bisulfite deaminates cytosine into uracil, but does not affect 5-methylcytosine, a methylated form of cytosine with a methyl group attached to carbon 5. When the bisulfite-treated DNA is amplified via polymerase chain reaction , the uracil is amplified as thymine and the methylated cytosines are amplified as cytosine.

  4. Sodium bisulfite - Wikipedia

    en.wikipedia.org/wiki/Sodium_bisulfite

    It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide. Regardless of its ill-defined nature, sodium bisulfite is used in many different industries such as a food additive with E number E222 in the food industry, a reducing agent in the cosmetic industry, and a decomposer of residual hypochlorite used in the ...

  5. Sodium bisulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bisulfate

    Sodium bisulfate, also known as sodium hydrogen sulfate, [a] is the sodium salt of the bisulfate anion, with the molecular formula NaHSO 4.Sodium bisulfate is an acid salt formed by partial neutralization of sulfuric acid by an equivalent of sodium base, typically in the form of either sodium hydroxide (lye) or sodium chloride (table salt).

    Forms Data Format is defined in the PDF specification (since PDF 1.2). The Forms Data Format can be used when submitting form data to a server, receiving the response, and incorporating it into the interactive form. It can also be used to export form data to stand-alone files that can be imported back into the corresponding PDF interactive form.

  7. Bismuth - Wikipedia

    en.wikipedia.org/wiki/Bismuth

    In strongly acidic aqueous solution, the Bi 3+ ion solvates to form Bi(H 2 O) 3+ 8. [54] As pH increases, the cations polymerize until the octahedral bismuthyl complex [Bi 6 O 4 (OH) 4] 6+, [55] often abbreviated BiO +. Although bismuth oxychloride and bismuth oxynitrate have stoichiometries suggesting the ion, they are double salts instead. [56]

  8. Acidic oxide - Wikipedia

    en.wikipedia.org/wiki/Acidic_oxide

    Carbonic acid is an illustrative example of the Lewis acidity of an acidic oxide. CO 2 + 2OH − ⇌ HCO 3 − + OH − ⇌ CO 3 2− + H 2 O. This property is a key reason for keeping alkali chemicals well sealed from the atmosphere, as long-term exposure to carbon dioxide in the air can degrade the material.

    An example is a tax return; filling one out is required in order for the amount of tax one owes to be determined. A form may also be a request for a tax refund. Forms may be filled out in duplicate (or triplicate, meaning three times) when the information gathered on the form needs to be distributed to several departments within an organisation.
