Question

Why can not each metal react to it its own salt

Answer 1

In a displacement reaction, a more reactive metal can displace a less reactive metal from its salt solution. ...The elements potassium, sodium, lithium and calcium are very reactive and they react with cold water to produce hydroxides and hydrogen gas. That is why each metal react to its own salt.
