Single Displacement of Mn and Cr from solution with Mg

Following the reactivity series can magnesium displace manganese metal from manganese salt solution

Also could chromium also be extracted from its salt solution

Found that magnesium can replace zinc in zinc chloride
Although aluminum cant

Magnesium also displaces iron metal from iron chloride

This belongs in Beginnings.

This is experimently testing the reactions not homework btw I know the reactivity series says its possible some reactions prove it wrong such as aluminum does not displace zinc from zinc chloride

I apologize if this is in the wrong section

I know both can be made through thermite reaction
Just not sure if it can be done from solution

Not sure if anyone has attempted these reactions

Generally questions that do not have any references of some kind are placed in beginnings.

I'm honestly not sure about your question in practice. In theory though, Magnesium is so reactive it can displace H+ from water, so I imagine that it could easily displace Mn or Cr as long as they were solublised. Quite a lot of the Mg will be consumed by it's reaction with water though.
