uses it is used in the manufacture of ammonia, to produce nitric acid and subsequently used as a fertilizer. nitric acid salts include important compounds like potassium nitrate, ammonium nitrate, and nitric acid. nitrated organic compounds such as nitro glycerine are often explosives. liquid ...
(as when one of the constituents is potassium dichromate). Analyzing a wine for sulfur dioxide requires iodine for oxidation; therefore, starch is used as the indicator (which forms a blue starch-iodine complex in the presence of excess iodine). However, color change is often a sufficient ...
