Webb20 juli 2024 · In Binary Ionic Compounds and Their Properties we point out that when an ionic compound dissolves in water, the positive and negative ions originally present in the crystal lattice persist in solution. WebbNiCl2 is polar. Electronegativity is the strength with which an atom pulls on shared electrons. Is NiCl2 a precipitate? Yes. you see. Because solid NiCl 2 dissociates to nickel +2 ions and chloride ions in water. Then, nickel +2 ion and hydroxyl ions form nickel hydroxide precipitate. What ions are present in aqueous solution of NiCl2?
