Aqua vs Hydrate
Is it aqua if it is directly connected to the coordination compound while it is called hydrate if it is not? Is there anymore examples of like differing names compared to the original atomic name?

Re: Aqua vs Hydrate
Yes I think I saw in another chemistry community post that when H2O is within the coordination compound, it's name is aqua. For example, in the coordination compound [CrCl3(NH3)2(OH2)]+ , H2O would be referred to as aqua. When outside of the bracket, H2O is referred to as hydrate. Honestly, I'm not sure if there are any other differing names.

Yes, you are correct. Aqua is when it is part of the coordination sphere, while hydrate is when it is outside the cor=ordination sphere.

Yes, if the water is acting as a ligand within the coordination sphere (inside the brackets) it is referred to as 'aqua.' When it is outside the coordination sphere it is 'hydrate' (with the appropriate prefix.)

Re: Aqua vs Hydrate
I noticed that oh2 is also considered aqua if it is in the coordination compound is that true?

yeah I think that's what other people above were referring to

You are correct, H2O is aqua when it's in the coordination compound and hydrate when it isn't.

I think it would still be aqua. For example, [Co(CN)5(OH2)]2- is an anion and is called aquapentatecyanocobaltate (III) ion.

Yes, you're correct, in the coordination compound H2O is aqua and when it isn't in the coordination compound it is hydrate.

It will still be aqua, -ate is only added to the end of metal name if the complex is an anion.

Re: Aqua vs Hydrate
Hi! You're right: aqua refers to water when the compound is within the square brackets and hydrate refers to water outside the square brackets.

Re: Aqua vs Hydrate
if its aqua, the water molecule acts as a ligand and is directly bound to the transition metal ion by a coordinate covalent bond. If its hydrate, the water molecule exist our of the coordination sphere

I dont know this either.
