A KS5 eduion resource on copper''s reactivity compared to other metals. Changes in the appearance of copper - patination. Reactivity Metals can be listed according to their reactivity. Some, like sodium, are so reactive that they explode on contact with water.
electrochemistry - What will be the reaction between tin …
Using basic electrochemistry, we know that Copper prefers to be copper metal. Due to its overbearing power over the tin(II) ion, the copper(II) ion forces the tin(II) ion to become tin(IV). I did not check the reduction or oxidation potential of the chloride ion (since the chloride ion is the most stable form of chlorine due to its (relative to the other compounds in this experiment) high
