    It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]

  3. Boric acid - Wikipedia

    en.wikipedia.org/wiki/Boric_acid

    Boric acid is a weak acid, with pK a (the pH at which buffering is strongest because the free acid and borate ion are in equal concentrations) of 9.24 in pure water at 25 °C. But apparent p K a is substantially lower in swimming pool or ocean waters because of interactions with various other molecules in solution.

    Boric acid has a pK a of 9.14 at 25 °C. Applications. BBS has many uses because it is isotonic and has a strong bactericidal effect. [1] It can be used to dilute ...

  6. Borate esters - Wikipedia

    en.wikipedia.org/wiki/Borate_esters

    A dehydrating agent, such as concentrated sulfuric acid is typically added. [1] Borate esters are volatile and can be purified by distillation. This procedure is used for analysis of trace amounts of borate and for analysis of boron in steel. [2] Like all boron compounds, alkyl borates burn with a characteristic green flame.

    en.wikipedia.org/wiki/Boric

    Boric is a chemistry term that refers to substances containing boron, such as: boric acid or orthoboric acid, B(OH) 3; metaboric acid, an acid containing boron, HBO 2; tetraboric acid or pyroboric acid, an acid containing boron, H 2 B 4 O 7; boric oxide, specifically boron trioxide B 2 O 3; a boric ester, or organic borate; Boric may also refer to:

  8. Rosocyanine - Wikipedia

    en.wikipedia.org/wiki/Rosocyanine

    Rosocyanine is a dark green solid with a glossy, metallic shine that forms red colored solutions. It is almost insoluble in water and some organic solvents, very slightly soluble (up to 0.01%) in ethanol, and somewhat soluble (approximately 1%) in pyridine, sulfuric acid, and acetic acid.

  9. Calcium borate - Wikipedia

    en.wikipedia.org/wiki/Calcium_borate

    It can be prepared by reacting calcium metal with boric acid. The resulting precipitate is calcium borate. A hydrated form occurs naturally as the minerals colemanite, nobleite and priceite. [citation needed] One of its uses is as a binder in some grades of hexagonal boron nitride for hot pressing.
