Write the formulae for the following coordination compounds.
Tetraamminediaquacobalt(III) chloride

Explanation

`("Tetraamminediaqua")/("Ligand")("cobalt (III)")/("Metal")("chloride")/("Counter ion")`
`[overset("III")(Co)(NH_(3))_(4)(H_(2)O)_(2)]Cl_(x)`
To find the value of x, we have no find the charge on the complex.
`[overset("III")(Co)(NH_(3))_(4)(H_(2)O)_(2)]^(+)`
`+3+4xx0+2xx0=xrArrx=+3`
So, the formula of the complex is
`[Co(NH_(3))_(4)(H_(2)O)_(2)]Cl_(3)`.
