What is Copper Reactions with Nitric Acid about?

1. Chemical reactions occur when chemical bonds are broken and new bonds are formed, producing one or more new substances. 2. Copper reacts with concentrated nitric acid, forming copper (II) ions and emitting a toxic gas. Sodium hydroxide is then added to form a copper (II) hydroxide precipitate. 3. The copper (II) hydroxide is heated to form copper (II) oxide, which dissolves when sulfuric acid is added, forming a colored solution. Zinc dust is added to reduce the copper ions back to metallic copper.
