When Ni(NO3)2 is dissolved in H2O (water) it will dissociate (dissolve) into Ni+2 and 2NO3- ions. The (aq) shows that they are aqueous – dissolved in water. Click to see full answer.
What is the name of the compound Ni (NO3) 2?
Nickel nitrate is the inorganic compound Ni(NO3)2 or any hydrate thereof. The anhydrous form is not commonly encountered, thus "nickel nitrate" usually refers to nickel(II) nitrate hexahydrate. The formula for this species is written in two ways.
What happens when Na2S is added to Ni (NO3) 2?
Here, sodium sulfide (Na2S) is added to nickel(II) nitrate (Ni(NO3)2). The result is a black precipitate. Show Stills
What happens when concentrated ammonia solution is added to Ni2+ solution?
When concentrated ammonia solution is added to the aqueous green colour Ni 2+ solution ( Ni (NO 3) 2 or NiCl 2 ), blue colour hexaamminenickel (ii) ion ( [Ni (NH3)6]2+ ) is given. If dilute ammonia solution is added instead of concentrated ammonia solution, first a green colour precipitate is given.
What is the formula for Ni (H2O) 6?
The formula for this species is written in two ways: Ni (NO 3) 2. 6H 2 O and, more descriptively [Ni (H 2 O) 6 ] (NO 3) 2. The latter formula indicates that the nickel (II) center is surrounded by six water molecules in this hydrated salt.
Is Ni no3 2 a solid liquid or gas?
crystalline solidNickel nitrate is a green crystalline solid.
Is Ni no3 2 a precipitate?
No, a precipitate will not form. There will be no reaction that takes place between nickel nitrate and sodium sulfate.
What type of reaction is Ni no3 2?
Ni(NO 3) 2 is an oxidizing agent, Ni(NO 3) 2 is a reducing agent. This is a precipitation reaction: NiO is the formed precipitate. This is a gas evolution reaction, O 2 is the formed gas.

Is NiS soluble in water?
About Nickel Sulfide NiS Nickel Sulfide is a moderately water and acid soluble Nickel source for uses compatible with sulfates.
Is nickel hydroxide a solid?
Nickel(II) hydroxide is the inorganic compound with the formula Ni(OH)2. It is an apple-green solid that dissolves with decomposition in ammonia and amines and is attacked by acids.
Is NiCO3 soluble in water?
Nickel carbonate is available primarily as basic nickel carbonate (NiCO3· 2Ni(OH)2 · 4H2O), which is not soluble in water and soluble in ammonia and dilute acids.
Is nickel sulfate soluble?
Nickel Sulfate is a moderately water and acid soluble Nickel source for uses compatible with sulfates.
Is nickel hydroxide soluble?
Nickel hydroxide appears as a fine green powder. Slightly soluble in water and denser than water.
Is Ni no2 2 water soluble?
Slightly soluble in water.
Is nickel soluble?
Solubility of nickel and nickel compounds Elementary nickel is water insoluble at T=20oC pressure = 1 bar. However, nickel compounds may be water soluble. Nickel chloride is most water soluble; 553 g/L at 20oC, to 880 g/L at 99.9oC.
Is magnesium nitrate soluble in water?
Magnesium nitrate is also called Magnesium dinitrate or Magniosan or Nitromagnesite (hexahydrate). It is widely used in pyrotechnics. Magnesium dinitrate is a hygroscopic, crystalline solid white. It is highly soluble in water as well as ethanol and occurs naturally in caverns and mines.
How is nickel nitrate prepared?
It is prepared by the reaction of nickel oxide with nitric acid: The anhydrous nickel nitrate is typically not prepared by the heating the hydrates. Rather is generated by reaction of hydrates with dinitrogen pentoxide or of nickel carbonyl with dinitrogen tetroxide:
Is nickel nitrate a carcinogen?
It is also irritating to the eyes, skin and, upon inhalation of the dust, respiratory tract. It may cause skin allergy. Nickel nitrate is a carcinogen, along with most other nickel compounds.
Nickel ion solution and ammonia solution reaction
When concentrated ammonia solution is added to the aqueous green colour Ni 2+ solution ( Ni (NO 3) 2 or NiCl 2 ), blue colour hexaamminenickel (ii) ion ( [Ni (NH3)6]2+ ) is given.
Nickel ion and dilute ammonia solution reaction
If aqueous dilute ammonia solution is added to the Ni 2+ ion, a green precipitate, nickel hydroxide ( Ni (OH) 2) is given.
