Reaction of copper sponge containing iron filings with acid
Thread Content
There are certain iron filings and a small amount of oxidized copper oxide in the copper sponge. When adding dilute sulfuric acid for washing, should the iron react with the sponge copper first, or should the copper oxide react with the iron first?
Upstairs, there is something wrong with your question. Do you want to ask?: Does iron react with dilute sulfuric acid first, or does copper oxide react with dilute sulfuric acid first? The iron should react with dilute sulfuric acid first.
Haha, yes, that’s the question I wanted to ask. I’m sorry I expressed it wrongly. I know the answer, thank you
