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 ...

In a nitrogen oxide process, sulfur dioxide is oxidized to sulfuric acid in an aqueous phase, with nitrogen oxides serving as oxygen carriers. Processes of this type include the lead chamber processes (e.g., Mills - Packard and Gaillard) and the tower processes (e.g., Curtius, Petersen, Kachkaroff, Matignon, Salsasserra, and Moritz).
