Explanation:
Hydrogen atom has one electron and one proton. When this atom loses its electron and is left with only one proton, it forms H

b) Copper is less reactive than hydrogen therefore it does not react with acids to liberate hydrogen.
However in the presence of lactic acid in buttermilk the copper does not liberate hydrogen but due to oxidizing property of acid it gets oxidized to Cu

+ and thus leaches out to buttermilk and gets spoilt.
