Problem

A complex has a composition corresponding to the formula

\text{CoBr}_2\text{Cl} \cdot 4\text{NH}_3

. What is the structural formula if conductance measurements show two ions per formula unit? Silver nitrate solution given an immediate precipitate of

\text{AgCl}

but no

\text{AgBr}

. a.

[\text{CoBrCl}(\text{NH}_3)_4]\text{Br}

[\text{CoCl}(\text{NH}_3)_4]\text{Br}_2

[\text{CoBr}_2\text{Cl}(\text{NH}_3)_4]

[\text{CoBr}_2(\text{NH}_3)_4]\text{Cl}
