What is aggregation state?

We are not allowed to give answers straightaway. Those are standard reactions by the way.

I can get you started on the first one. Initially a water soluble complex is formed, which can be dehydrated to a meta-aluminate.
Second and third reactions have to do with metallurgy.
The words i have used in this post are key words, so you can google them to find the answers.

Not sure what you mean by aggregation state, but the reactions listed are clearly redox reaction as you have either well known reducing or oxidising agents as reactants. I think you should be able to work out the answer base on this clue. Reaction (a), however, is an exception and it produces a water-soluble complex.
