The actual nitrogen oxide formed depends on the concentration and temperature of the acid. There are actually two equations for the reaction of copper with nitric acid. It depends on whether the nitric acid is concentrated or not. If it is concentrated and in excess then the ratio is 1:4 copper to nitric acid. If it is dilute then the ratio is 3:8.

Making copper(II) sulfate crystals from copper(II) oxide and dilute sulfuric acid. Start by watching this YouTube video. There is one slight oddity about this video in the way he demonstrates folding a filter paper. He over-folds it in the demo, but when he fits it into the filter funnel, it is folded properly! ...
Two oxides are considered: sulfur dioxide, SO 2, and sulfur xide, SO 3. Sulfur dioxide: Sulfur dioxide is fairly soluble in water, reacting to give a solution of sulfurous acid (also known as sulfuric(IV) acid), H 2 SO 3, as shown in the reaction below. This species only exists in solution, and any attempt to isolate it gives off sulfur ...
Metal oxides act as base. So, they neutralise acid to give salt and water. So, copper oxide will react with sulfuric acid. Metal hydroxides are bases. So, they will neutralise acids. So, copper hydroxide will react with dilute sulfuric acid. Carbonates react with acids to give salt, carbon dioxide and water. So, copper carbonate will react with ...
