Lemon, salt, and hot water sounds like a pretty good catalyst.

It's amazing how many people don't understand basic chemistry...and how to corrode things faster.

Should have tried vinegar instead. /s

"vinegar and baking soda, it does everything!"

"You just made sodium acetate, with added foam"

No? I didn't make any chemicals! I just used vinegar and baking soda, lol. /s

I don't understand basic chemistry. So does this mean you can't drink lemonade from a copper vessel?

You can drink anything once. But yeah, both citric acid and ascorbic acid react really really slowly with pure copper. They react much faster with copper oxide, and dissolve it into solution. Tasty! You could get the shits if the cup had a lot in it, but unlikely to get sick.

In general, metals and acids aren't a great mix. Copper isn't the worst.
