Answer and worked solution
Official answer: 1
1:1 electrolyte. The formula is , with one ionisable chloride outside the coordination sphere.
The key's reading. NTA's key counts the ionisable chlorides satisfying primary valency, which gives 1. (In Werner's terms, the primary valency equals cobalt's oxidation state, +3.)
