Production of weak nitric acid In the United States, most of the nitric acid is created by the high-temperature catalytic oxidation of ammonia. A good buffer is a mixture of a weak acid and its salt with strong base. Explosively decomposed at over 130°C [Merck 11th ed. Step#2 - carbonate is CO 3 2 ¯. Three of the children and one adult also received calcium chloride in the same injection. KOH- strong base. In a xenon detector, dye deposited as a monolayer and only brightest spots at constant depth expected. Barium hydroxide is used in analytical chemistry for the titration of weak acids, particularly organic acids. The conjugate acid is hypochloric acid. Four perchlorates are of primary commercial interest: ammonium perchlorate (NH 4 ClO 4 ), perchloric acid (HClO 4 ), potassium perchlorate (KClO 4 ), and sodium perchlorate (NaClO 4 ).
