Reactivity Series Of Metal

Metals has its reactivity arranged from the highest to lowest like this:

For example, since Aluminum is more reactive than Silver, we can put salt of Silver with Aluminum and after reaction finished, we’ll have salt of Aluminum and Silver.

I was cleaning my silver chain today using this method. I added vinegar to start the oxidization process, and the Aluminum helped “cleaned” my silver chain.

I feel like this can be helpful for a detective so I include this piece of information here.
