Question

I need help ASAP!:/ I am working on a chem lab but I don't have the materials in my home to do so. Can someone help me with the following questions;

1.) What happens when you leave a Galvanized washer (zinc coated) in a cup of vinegar for 1 minute to 3 minutes then to 5 minutes?

2.) What happens when you leave a Iron washer (uncoated) in a cup of white vinegar for 1 minute to 3 minutes then to 5 minutes?

Your help will be very appreciated.. Thank you.

Answer 1

1) nothing for that short amount of time since it's galvanized

2) agains, such a short amount of time, idk, it doesn't seem like much would happen.
though but you could expect that some of the iron will be corroded, maybe some dissolve into the acidic solution.

you should try to write equations for these processes

Answer 2

Thank you so much for the help!!
