Excerpt from Proceedings of the Twenty-Sixth Annual Convention of the Association of Official Agricultural Chemists: Held at Denver, Colorado, August 26-28, 1909 Moreover, unavoidable errors in analyses made for this purpose produce rather large variations in the final results, since a difference of cc of fourth-normal alkali would produce a variation of 40 cc fourth-normal ammonia per liter when cc of the citrate solution under examination are measured out for the determination. This corresponds approximately to cc of strong ammonia solution. In a similar way a difference of cc of fourth-normal alkali in the titration of the citric acid would correspond to about grams of citric acid per liter.
