  2. Sodium hypophosphite - Wikipedia

    en.wikipedia.org/wiki/Sodium_hypophosphite

    Sodium hypophosphite (NaPO 2 H 2, also known as sodium phosphinate) is the sodium salt of hypophosphorous acid and is often encountered as the monohydrate, NaPO 2 H 2 ·H 2 O. It is a solid at room temperature, appearing as odorless white crystals. It is soluble in water, and easily absorbs moisture from the air.

  3. Monosodium phosphate - Wikipedia

    en.wikipedia.org/wiki/Monosodium_phosphate

    The salt is obtained by partial neutralization of phosphoric acid. The pK a of monosodium phosphate is 6.8-7.2 (depending on the physicochemical characteristics during pK a determination). [2] Heating this salt above 169 °C gives disodium pyrophosphate: 2 NaH 2 PO 4 → Na 2 H 2 P 2 O 7 + H 2 O. When heated at 550 °C, anhydrous trisodium ...

  4. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    An amphiprotic molecule (or ion) can either donate or accept a proton, thus acting either as an acid or a base. Water, amino acids, hydrogencarbonate ion (or bicarbonate ion) HCO − 3, dihydrogen phosphate ion H 2 PO − 4, and hydrogensulfate ion (or bisulfate ion) HSO − 4 are common examples of amphiprotic species. Since they can donate a ...

    Meat “Meat is a staple in many people’s diets and is rich in nutrients that may aid hair growth. The protein in meat aids growth and helps repair and strengthen hair follicles,” says Gomer.

  6. Sodium compounds - Wikipedia

    en.wikipedia.org/wiki/Sodium_compounds

    Because of the high solubility of its compounds, sodium salts are usually isolated as solids by evaporation or by precipitation with an organic antisolvent, such as ethanol; for example, only 0.35 g/L of sodium chloride will dissolve in ethanol. [15] Crown ethers, like 15-crown-5, may be used as a phase-transfer catalyst. [16]

  7. Sodium phosphate - Wikipedia

    en.wikipedia.org/wiki/Sodium_phosphate

    A sodium phosphate is a generic variety of salts of sodium (Na +) and phosphate (PO 3− 4). Phosphate also forms families or condensed anions including di-, tri-, tetra-, and polyphosphates. Most of these salts are known in both anhydrous (water-free) and hydrated forms. The hydrates are more common than the anhydrous forms. [1]

  8. Microcosmic salt - Wikipedia

    en.wikipedia.org/wiki/Microcosmic_salt

    The first extraction of pure phosphorus came from this salt in the 17th century, when Hennig Brandt attempted to extract gold from urine. Microcosmic salt is used in the laboratory as an essential ingredient of the microcosmic salt bead test for identification of metallic radicals on the basis of the color they produce in oxidizing or reducing ...

  9. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    This means that salts of the mono- and di-phosphate ions can be selectively crystallised from aqueous solution by setting the pH value to either 4.7 or 9.8. In effect, H 3 PO 4, H 2 (PO 4) − and H(PO 4) 2− behave as separate weak acids because the successive pK a differ by more than 4. Phosphate can form many polymeric ions such as ...
