    Cupcakes baked with baking soda as a raising agent. Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3.

  3. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above. However, solutions of NaOH can be easily supercooled by many degrees, which ...

    3 I 2 + 6 NaOH → NaIO 3 + 5 NaI + 3 H 2 O. Reactions. Sodium iodate can be oxidized to sodium periodate in water solutions by hypochlorites or other strong ...

  5. Sodium hydride - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydride

    Sodium hydride is the chemical compound with the empirical formula Na H.This alkali metal hydride is primarily used as a strong yet combustible base in organic synthesis.NaH is a saline (salt-like) hydride, composed of Na + and H − ions, in contrast to molecular hydrides such as borane, silane, germane, ammonia, and methane.

  6. Hydroxide - Wikipedia

    en.wikipedia.org/wiki/Hydroxide

    The hydroxide ion appears to rotate freely in crystals of the heavier alkali metal hydroxides at higher temperatures so as to present itself as a spherical ion, with an effective ionic radius of about 153 pm. [38] Thus, the high-temperature forms of KOH and NaOH have the sodium chloride structure, [39] which gradually freezes in a ...

    en.wikipedia.org/wiki/Thiourea

    Thiourea (/ ˌ θ aɪ. oʊ j ʊəˈr iː. ə,-ˈ jʊər i-/) [2] [3] is an organosulfur compound with the formula SC(NH 2) 2 and the structure H 2 N−C(=S)−NH 2.It is structurally similar to urea (H 2 N−C(=O)−NH 2), with the oxygen atom replaced by sulfur atom (as implied by the thio-prefix).

  8. Sodium acetate - Wikipedia

    en.wikipedia.org/wiki/Sodium_acetate

    CH 3 COOH + NaOH → CH 3 COONa + H 2 O. To manufacture anhydrous sodium acetate industrially, the Niacet Process is used. Sodium metal ingots are extruded through a die to form a ribbon of sodium metal, usually under an inert gas atmosphere such as N 2 then immersed in anhydrous acetic acid. 2 CH 3 COOH + 2 Na →2 CH 3 COONa + H 2.
