Nature with most metals (reactive than copper), and the vast majority of the metal oxide reacts corresponding sulfate and water; ion contained in correspondence with weak acid salt than the sulfate ions react superior grade nitric acid to produce the corresponding sulfates and weak acid; with a base to generate the corresponding sulfates and water; the metal with hydrogen before reaction under conditions effective nitrate to form the corresponding sulfates and hydrogen; under heating conditions can catalyze protein, disaccharides and polysaccharides hydrolysis; with indicator effect, so that red and purple litmus test solution, so colorless phenolphthalein test solution does not change color.
