Chemical Class and Type: Copper sulfate is an algaecide, bactericide, and fungicide. When it is mixed with calcium hydroxide it is known as Bordeaux mixture. 1 The International Union of Pure and Applied Chemistry IUPAC name for this active ingredient is copper 2+ sulfate or copper II sulfate. Other names include copper 2+ tretraoxidosulfate or copper II tretraoxidosulfate. 2

The Chemistry of Patination The first step in the development of a patina is oxidation to form copper I oxide which has a red or pink colour equation 1, when copper atoms initially react with oxygen molecules in the air. Copper I oxide is further oxidized to copper II oxide CuO, which is black in color …

Note: Until I added the questions in July 2015, I had always assumed on no good evidence - never a good idea! that chalcopyrite contained copper and iron both in the +2 oxidation state - but that may well be wrong. If it was true, then you can show that the sulphide ions are reducing CuII to CuI. However, if the copper was in the +1 state originally, then the sulphide ions are reducing ...
