• Acidic
  • Acidic foods and beverages such as fruit juice (citric acid), sparkling drinks (carbonic acid), soft drinks (phosphoric acid), and pickles (vinegar) may be preserved with potassium benzoate. (wikipedia.org)
  • They are about ten times more acidic than the parent benzoic acid. (wikipedia.org)
  • The value at zero ionic strength is difficult to determine because half dissociation only occurs in very acidic solution, at about pH 0, that is, with an acid concentration of about 1 mol dm−3. (wikipedia.org)
  • bonds
  • Chromic acid is capable of oxidizing many kinds of organic compounds and many variations on this reagent have been developed: Chromic acid in aqueous sulfuric acid and acetone is known as the Jones reagent, which will oxidize primary and secondary alcohols to carboxylic acids and ketones respectively, while rarely affecting unsaturated bonds. (wikipedia.org)
  • known
  • Because a solution of chromic acid in sulfuric acid (also known as a sulfochromic mixture or chromosulfuric acid) is a powerful oxidizing agent, it can be used to clean laboratory glassware, particularly of otherwise insoluble organic residues. (wikipedia.org)
  • Structure
  • Dichromic acid, H2Cr2O7, (structure illustrated top right) is the fully protonated form of the dichromate ion and also can be seen as the product of adding chromium trioxide to molecular chromic acid. (wikipedia.org)
  • ability
  • As the sodium salt form, sodium benzoate is used as a treatment for urea cycle disorders due to its ability to bind amino acids. (drugbank.ca)
  • Chromic acid was widely used in the instrument repair industry, due to its ability to "brighten" raw brass. (wikipedia.org)
  • soft
  • These nucleophiles are then subdivided into "hard" and "soft" nucleophiles using a paradigm for describing nucleophiles that largely rests on the pKas of their conjugate acids. (wikipedia.org)
  • Hard" nucleophiles typically have conjugate acids with pKas greater than 25, while "soft" nucleophiles typically have conjugate acids with pKas less than 25. (wikipedia.org)
  • changes
  • At first the colour changes from orange (dichromate) to red (chromic acid) and then deep red crystals of chromium trioxide precipitate from the mixture, without further colour change. (wikipedia.org)
  • medium
  • This reaction is catalyzed by the HXM-A and HXM-B medium-chain acid:CoA ligases and requires energy in the form of ATP. (wikipedia.org)
  • It is a Lewis acid and can react with a Lewis base, such as pyridine in a non-aqueous medium such as dichloromethane (Collins reagent). (wikipedia.org)
