It is made by reaction of a little sodium hydroxide with phosphoric acid. When the phosphate donor is phosphoric acid, its amount is about 0.6mol per 1mol of dissolved calcium, and the pH of the system is maintained usually to about 8-11. A pH between 12 and 13 gives the most stable solution. Country of … Biological buffers are inert and have short-term effects on the system under investigation, both of which are distinct advantage over inorganic substances and weak organic acids that were used in the past. (pH=14) Dans nos essais de dosages spectrométriques, nous passons bien d'une solution de couleur violette (permanganate) à verte (manganate). 2021-01-02.
