What is the chemical reaction if…?

What would happen if I get a lime and put a little bit of copper foil over it and wrap around it with a thick thread and leave it in a 2 litre bottle full of water for 3 nights? Would the lime and foil disappear?

    the pH of lime juice = 2-2.4
    Cu is not readily reactive to HCl it takes a realtviely high concentration of H+ to react with the Cu. plus, adding it to water will only dilute the acid from the lime. nothing will happen.

    The lime would react with the water to produce calcium hydroxide.
    CaO + H2O –> Ca(OH)2
    This is only just slightly soluble in water.
    So, the solution would become slightly milky with a pH of just over 7 and some of the white Ca(OH)2 would sink to the bottom.
    Nothing would happen to the copper.
