### What drives double displacement reactions?

Dissolved salts exist as separated, hydrated ions, moving and reacting independently. (*) Like for $\ce{Zn}$ and $\ce{CuSO4}$: The reaction is $\ce{Zn(s) + Cu^2+(aq) -> Zn^2+(aq) + Cu(s)}$. The ...

### Completely chemically inert metal alloy?

The problem is that in different media different metals / alloys are so corrosion resistant than we regard them as being "inert". It is interesting that aluminium in strong nitric acid is ...

### Completely chemically inert metal alloy?

Not the best source but Wikipedia says that Iridium is one of the most corrosive resistant metal elements (I believe I have seen it referred to as "the most" elsewhere). Only some molten ...

### What are good ways to anticipate co-crystalization of different metal ions?

Major factors for coprecipitation are shared valency, similar ionic radius, shared relevant chemistry regarding counter-ions. Like Al, Cr and Fe(III) in alums. Note the various forms of co-...
