Oxalic acid and its salts occur as end products of metabolism in a number of plant tissues. When these plants are eaten they may have an adverse effect on mineral bioavailability because oxalates bind calcium and other minerals. While oxalic acid is a normal end product of mammalian metabolism...Table 6.1 : Titration of potassium permanganate solution against standard oxalic acid solution Sl. No. Volume of Oxalic acid in mL Burette readings Volume (V) of KMnO4 used V = (y–x) mL Initial (x) Final (y) Calculations (i) The strength of the unknown solution in terms of molarity may be determined by the following equation. = a 2 (6.1 ... oxalic acid. Theory In the titration of a strong acid with a strong base, the amount of acid and base becomes chemically equivalent at the end point and the chemical reaction is called neutralization reaction. Near the end point there is a sudden change in the pH of the solution. If after end point even a small amount of base/acid is added the For the preparation of 1 litre of N/20 oxalic acid solution amount of oxalic acid is required is 12.6g. Following steps should be followed - 1. Weigh 12.6 g of oxalic acid using a weighing machine. 2. Now take the weighed oxalic acid in a measuring flask and add distilled water to make the volume 1litre. 3. Acetic acid (CH 3 COOH), also called ethanoic acid, the most important of the carboxylic acids.A dilute (approximately 5 percent by volume) solution of acetic acid produced by fermentation and oxidation of natural carbohydrates is called vinegar; a salt, ester, or acylal of acetic acid is called acetate.

Scientific American Supplement, No. 832, December 12, 1891. Concentrated nitric acid highly charged with this substance is called _fuming nitric acid_. An Elementary Study of Chemistry
In the analysis of vinegar, the concentration of the solute (acetic acid) was determined from the amount of reactant that combined with the solute present in a known volume of the solution. In other types of chemical analyses, the amount of a substance present in a sample is determined by measuring the amount of product that results.
