    NaHCO 3 + HCl → NaCl + H 2 O+CO 2 H 2 CO 3 → H 2 O + CO 2 (g) Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide: NaHCO 3 + CH 3 COOH → CH 3 COONa + H 2 O + CO 2 (g) Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates: NaHCO 3 + NaOH → Na 2 CO 3 ...

  3. Hydroxylammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Hydroxylammonium_chloride

    Hydroxylammonium chloride is a chemical compound with the formula [NH 3 OH] + Cl −.It is the hydrochloric acid salt of hydroxylamine (NH 2 OH).Hydroxylamine is a biological intermediate in nitrification (biological oxidation of ammonia with oxygen into nitrite) and in anammox (biological oxidation of nitrite and ammonium into dinitrogen gas) which are important in the nitrogen cycle in soil ...

    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 ...

    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).

  6. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na 2 CO 3 and its various hydrates.All forms are white, odourless, water-soluble salts that yield alkaline solutions in water.

  7. Alkali–silica reaction - Wikipedia

    en.wikipedia.org/wiki/Alkali–silica_reaction

    Ca(OH) 2 + H 4 SiO 4 → Ca 2+ + H 2 SiO 4 2− + 2 H 2 O → CaH 2 SiO 4 · 2 H 2 O. Here, the silicic acid H 4 SiO 4, or Si(OH) 4, which is equivalent to SiO 2 · 2 H 2 O represents hydrous or amorphous silica for the sake of simplicity in aqueous chemistry. Indeed, the term silicic acid has traditionally been used as a synonym for silica, SiO 2.
