Not Counting Subscripts?

Postby Frederick Keith_4C » Sun Dec 01, 2019 11:32 am

The compound is : [Co (NH3)3 (H2O)3]2 (SO4^-2)3
The ligands are ammonia and water.
The name is Triaminetriaquacobalt (III) sulfate
How come its only "tri" when there is a 2 subscript? Shouldn't they all be multiplied by 2 and the name should have prefixes for "six" instead of "three?"

The tri is referring to the number of ammonia molecules; since there are only three, the name remains triaminetriaquacobalt.
