The formation of a complex ion involving cobalt and chloride ions typically involves the coordination of chloride ions to a cobalt ion. For example, one common complex ion formed is the hexachlorocobalt(II) ion, represented as \([CoCl_6]^{2-}\).
The general chemical equation for the formation of this complex can be written as:
\[
Co^{2+} + 6Cl^- \rightarrow [CoCl_6]^{2-}
\]
In this reaction, one cobalt ion with a +2 charge coordinates with six chloride ions, resulting in the formation of a complex ion with a -2 charge.
