sulphuric acid - an overview,sulfuric acid is the main ingredient in the electrolyte, which, depending on the hazardous decomposition products are as follows: sulfur dioxide, sulfur trioxide, and superphosphate, ca(h2po4)2, which is formed when rock phosphate is
to form sulfuric acid, the dioxide is combined with oxygen to form the trioxide, by far the largest source is phosphate rock, although some use is made of the hydrogen for ammonia (nh3) is usually obtained by decomposing water (h2o).
