Glacial acetic acid is used in analytical chemistry for the estimation of weakly alkaline substances such as organic amides. Glacial acetic acid is a much weaker base than water, so the amide behaves as a strong base in this medium. It then can be titrated using a solution in glacial acetic acid of a very strong acid, such as perchloric acid. [52]
If the glacial acetic acid is replaced by 5 ml of formalin (37–40% formaldehyde), the resulting solution is Helly's fixative, also sometimes called "formol-Zenker".Helly is stable for only a few hours because the formaldehyde and dichromate components react, producing formic acid and chromium(III) ions; the orange solution becomes greenish.
Peracetic acid (also known as peroxyacetic acid, or PAA) is an organic compound with the formula CH 3 CO 3 H. This peroxy acid is a colorless liquid with a characteristic acrid odor reminiscent of acetic acid. It can be highly corrosive. Peracetic acid is a weaker acid than the parent acetic acid, with a pK a of 8.2. [2]
TAE buffer is commonly prepared as a 50× stock solution for laboratory use. A 50× stock solution can be prepared by dissolving 242 g Tris base in water, adding 57.1 ml glacial acetic acid, and 100 ml of 500 mM EDTA (pH 8.0) solution, and bringing the final volume up to 1 litre.
In hemocytometry, Türk's solution (or Türk's fluid) is a hematological stain (either crystal violet or aqueous methylene blue) prepared in 99% acetic acid (glacial) [1] and distilled water. The solution destroys the red blood cells and platelets within a blood sample (acetic acid being the main lyzing agent ), and stains the nuclei of the ...
Bromothymol blue is synthesized by addition of elemental bromine to thymol blue in a solution in glacial acetic acid. [6] To prepare a solution for use as pH indicator, dissolve 0.10 g in 8.0 cm 3 N/50 (a.k.a. 0.02 Normal) NaOH and dilute with water to 250 cm 3. To prepare a solution for use as indicator in volumetric work, dissolve 0.1 g in ...
Ammonium acetate, also known as spirit of Mindererus in aqueous solution, is a chemical compound with the formula NH 4 CH 3 CO 2. It is a white, hygroscopic solid and can be derived from the reaction of ammonia and acetic acid. It is available commercially. [5]
