Just how does copper kill germs? - EOScu

As the oxidizing copper atoms break down the cell wall, the bacteria attempts to adapt to the environment by taking in from its surroundings or pushing unneeded elements out. As a result, the copper ions flood into the cell. Copper is quickly toxic to the inside of the cell, which is full of fragile, DNA-making parts.

Transformation of Copper: A Sequence of Chemical Reactions

Copper oxide dissolves in acid, regenerating the copper (II) ion, which once again binds to water.CuO (s) + 2 H 3 O + (aq) + 3 H 2 O (l) --> [Cu(H 2 O) 6] 2+ (aq) Finally, zinc metal reduces the hydrated copper (II) ion back to metallic copper while itself turning being oxidized to zinc (II) ions. We have seen this reaction before in the copper ...
