Question

why can not each metal react to itd own salt sg cu and cuso4?

Answer 1

hey mate!!

each metal does not react with its own salt because they both possess same properties and the cannot replace one another.

hope it helped!

Answer 2

Reaction of metal with salt is a displacement reaction. It goes like :

Metal A +salt solution of B=>metal B+salt solution of A .

In this A is more reactive than B .

Since , a metal can not displace it self so it can not react to it's own salt. For e.g. copper can not displace it self in CuSo4.
