Question

Why can not each metal react to its own salt (Eg Cu and CuSo4

Answer 1

Hey dear,

● Explanation -

- For a metal to react with some specific salt, it must be more reactive than cation of the salt.

- But, when metal is treated with its own salt reactivity of both metal and cation from salt (same metal) is equal.

- Therefore, metals can't react with its own salt.

For example,

Cu + CuSO4 ---> NO REACTION
