Sulfuric acid GoldRefiningWiki

Sulfuric acid (also spelled sulphuric acid or in old texts as oil of vitriol) is one of the strong mineral acids and has a number of practical uses in refining.The acid differs from hydrocloric acid and nitric acid in that it contains two hydrogen atoms that can be ionized in water. This means that concentrated sulfuric acid and diluted can appear as two different acids.
