Acidic Wort Affect on Immersion Chiller and Flavor
I think that the acidity does not have an influence on copper, but it does on copper oxidation, which you do not want in your beer. Always clean and dry your chiller very well, and store it dry so ...

Can you increase the pH for the boil after kettle souring?
The lactic acid in the sour wort will act as a pH buffer and will mean quite a lot of "salts" will be needed to actually raise the pH of the wort. The lactic acid may well form a salt precipitate in ...
