Parts and what they mean

• [Ni(H₂O)₆]²⁺ — green ([Ni(H₂O)₆]²⁺ — हरा) — Forms when nickel(II) chloride dissolves in water.
• [Ni(H₂O)₄(en)]²⁺ — pale blue ([Ni(H₂O)₄(en)]²⁺ — हल्का नीला) — [Ni(H₂O)₆]²⁺ + en ⇌ [Ni(H₂O)₄(en)]²⁺ + 2H₂O (en:Ni = 1:1).
• [Ni(H₂O)₂(en)₂]²⁺ — blue/purple ([Ni(H₂O)₂(en)₂]²⁺ — नीला/बैंगनी) — [Ni(H₂O)₄(en)]²⁺ + en ⇌ [Ni(H₂O)₂(en)₂]²⁺ + 2H₂O (2:1).
• [Ni(en)₃]²⁺ — violet ([Ni(en)₃]²⁺ — बैंगनी) — [Ni(H₂O)₂(en)₂]²⁺ + en ⇌ [Ni(en)₃]²⁺ + 2H₂O (3:1). Each en replaces two H₂O.
