Cobalt Ions Form Complex Ions With Water And Chloride - Web hydroxide ions (from, say, sodium hydroxide solution) remove hydrogen ions from the water ligands attached to the cobalt ion. The addition of hydrochloric acid to the solution provides a high concentration of chloride. Web a solution of cobalt(ii) ion in water is pink, the color of the complex ion formed between co2+ ions and water molecules. A white background will help to show the colour. On the front cover, the pink colour in the test tube comes from cobalt (ii) ions in water, co (h 2 o) 62+. Web co 2+ + 6 h 2 o → [co (h 2 o) 6] 2+. Web however cobalt does not react with water that is at room temperature. Web pink cobalt species + chloride ions ⇌ blue cobalt species + water molecules. The simplest ion that cobalt forms in solution is the pink. Web due to the common ion effect, we might expect a salt such as agcl to be much less soluble in a concentrated solution of kcl.
