  2. Acetic acid - Wikipedia

    en.wikipedia.org/wiki/Acetic_acid

    Acetic acid can never be truly water-free in an atmosphere that contains water, so the presence of 0.1% water in glacial acetic acid lowers its melting point by 0.2 °C. [ 9 ] A common symbol for acetic acid is AcOH (or HOAc), where Ac is the pseudoelement symbol representing the acetyl group CH 3 −C(=O)− ; the conjugate base , acetate ( CH ...

  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  4. Potassium acetate - Wikipedia

    en.wikipedia.org/wiki/Potassium_acetate

    It can be prepared by treating a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid: . CH 3 COOH + KOH → CH 3 COOK + H 2 O. This sort of reaction is known as an acid-base neutralization reaction.

  5. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]

  6. Peracetic acid - Wikipedia

    en.wikipedia.org/wiki/Peracetic_acid

    Peracetic acid can be used as a cooling tower water disinfectant, where it prevents biofilm formation and effectively controls Legionella bacteria. Nu-Cidex is the trade name for a brand of antimicrobial peracetic acid.

  7. Sodium acetate - Wikipedia

    en.wikipedia.org/wiki/Sodium_acetate

    A supersaturated solution of sodium acetate in water is supplied with a device to initiate crystallization, a process that releases substantial heat. Solubility from CRC Handbook. Sodium acetate trihydrate crystals melt at 58–58.4 °C (136.4–137.1 °F), [12] [13] and the liquid sodium acetate dissolves in the released water of crystallization.

  8. pH indicator - Wikipedia

    en.wikipedia.org/wiki/PH_indicator

    In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...

  9. Calcium acetate - Wikipedia

    en.wikipedia.org/wiki/Calcium_acetate

    Calcium acetate is used as a food additive, as a stabilizer, buffer and sequestrant, mainly in candy products under the number E263. Tofu is traditionally obtained by coagulating soy milk with calcium sulfate. Calcium acetate has been found to be a better alternative; being soluble, it requires less skill and a smaller amount. [4]
