Question

Why can not each metal react to its own salt (Eg.Cu and Cuso4)?

Answer 1

because it's valency are same so it cannot react with each other

Answer 2

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

Hope this helps you...
