Hey, I need some help. Unfortunately, we barely finished the Shipwrecks topic and therefore haven't perfomed one of the first hand investigations, which is:

Perform a first hand investigation to compare and describe the rate of corrosion of metals in different acidic and neutral solutions.

Would someone be able to tell me the experiment procedure, equipment used and results is they don't mind.

I'd really appreciate the help.

set up fe nails in two test tubes, control all other variables but the pH... one be ~7 , the other be 4... obseve over a period of time...

Thanks for that.

you should observe that the rate of corrosion of the iron nails is faster in acidic environments (you can look at your table of reduction potentials and compare the oxidation potentials when h+ ispresent)
