The depression in freezing point of water observed for the same amount of acetic acid trichloroacetic acid and trifluoroacetic acid increases in the order given above. When the mouse pointer passes over the. The neutralising reaction can produce two salts - either the monosodium variety generally known simply as sodium salicylate where the proton from the carboxylic acid group is donated or the disodium one where both available protons are donated. Finally the benzoic acid will be precipitated by adding strong acid to the carboxylate salt solution.
