Dropping Paper and Copper into Acids

Dropping Paper and Copper into Acids

I was really curious about what would happen if you drop some paper and a weak metal (Copper) into strong acids. I only have 2 acids so that’s all I could do.

Hydrochloric acid:

Paper (A4 70 Grams) :


The paper started to fizz.


And after that, it ended and nothing happened. But the paper is mushy and soft.





Nothing happened with the copper. So I waited for one hour, but still, nothing happened.

Nitric Acid:


The same thing happened with the Hydrochloric acid…



The piece of copper dissolved very quickly and created this fumes which I think is called nitrogen dioxide (because of the orange vapor). And after that, there was only a green solution left in the beaker.


I think the Hydrochloric acid is less stronger than the Nitric Acid.

Thanks for reading.

I’m sorry that this was a short post.

  1. You’re welcome. 🙂
    And never mind – that’s life! You might find time for expts during the school holidays after you move to USA. 🙂

  2. Very interesting and such a great reaction of the copper with nitric acid. 🙂
    I’m sure you can find the answers via google – which I just did! It reacts here because nitric acid is an oxidising agent.
    Nice to see you back in the lab. 🙂
