Does Nickel form a precipitate when mixed with ammonia?
Yes. It is possible. With concentrated ammonia solution, nickel +2 first gives Ni(OH)2 green precipitate. With excess concentrated ammonia solution, precipitate dissolves and gives a blue colour solution.
What happens when you combine Nickel and chlorine?
Reactions with halogens Nickel reacts with chlorine, bromine and iodine to form nickel(II) dihalides.
What is the coordination number of nickel in ni NH3 6 2+?
M.Sc chemistry. In the both cases, the co-ordination number of nickel is six with octahedral geometry. The oxidation number of nickel is +2 with 3d8 system. Crystal field theory requires the splitting of the degenerate d-orbitals with the approaching of the ligands.
Is CO NH3 6 2+ high spin or low spin?
As NH3 is a strong field ligand, complex [Co(NH3)6]2+ is low spin, splitting energy ∆o is large.
How do you precipitate nickel?
Colorless sodium hydroxide solution is added to green nickel(II) nitrate solution. Approximately 2 mL of Solution A (on the left) is added to a sample of Solution B (on the right) with a dropping pipet. If a precipitate forms, the resulting precipitate is suspended in the mixture.
Which of the following is the correct chemical formula of nickel precipitate?
The experimental results show that nickel precipitates as nickel hydroxide (Ni(OH)2) starting at pH 3, being more evident at pH 9.
What does NH4+ and S2 make?
The compound (NH4)2S ( N H 4 ) 2 S is formed from the cation ammonium (NH+4 N H 4 + ) and the sulfide anion (S2− ). As a result, the name of this compound is ammonium sulfide.
What is the color of Ni NH3 6 2+?

What happens when ammonia is mixed with NiCl2?
Nickel (II) chloride react with ammonia NiCl 2 + 6NH 3 → [Ni (NH 3) 6 ]Cl 2 [ Check the balance ] Nickel (II) chloride react with ammonia to produce hexaamminenickel (II) chloride.
Can a nickel ion dissolve in concentrated ammonia?
Yes. It is possible. With concentrated ammonia solution, nickel +2 first gives Ni (OH) 2 green precipitate. With excess concentrated ammonia solution, precipitate dissolves and gives a blue colour solution. Zinc +2 ion gives a white precipitate ( Zn (OH) 2 ).
What is the chemical formula for nickel chloride?
Nickel(II) chloride (or just nickel chloride), is the chemical compound NiCl 2. The anhydrous salt is yellow, but the more familiar hydrate NiCl 2·6H 2O is green.
What happens when nickel ( II ) chloride reacts with water?
In the presence of water scavengers, hydrated nickel(II) chloride reacts with dimethoxyethane (dme) to form the molecular complex NiCl 2(dme) 2.
