A certain transition metal compound contains a cobalt ion

Reference no: EM13639004

A certain transition metal compound contains a cobalt ion ofunknown valence, ligands of water molecules, and chloride ions thatserve as counter ions. Consider a 0.256 gram sample of thetansition metal. filtered, dried and weighed, amounting to 0.308grams.A second sample of the transition metal complex weighing 0.416grams was dissolved in water and exccess NaOH added. The cobalthydroxide compund was isolated by filtration, washed , dried, in anoven and finally heated in a furnace to form cobalt(III) oxide. Themass of cobalt (III) oxide was 0.145 grams. What was the oxidation state of the cobalt in the complex ion and what was the formula of the cobalt-water-chloride compund?
