First of all, the ZN insertion filtrate is bubble-free, acid-free, and a mistake. Dilute sulfuric acid can react with copper oxide and iron, and it is possible that it reacts with both iron and copper oxide, so the cd term is written"There must be"If they are all wrong, then the b is correct. No matter who reacts with dilute sulfuric acid first, iron ions are more active than copper ions, so there must be ferrous sulfate.
