Does nickel chloride conduct electricity?
Yes, nickel chloride can conduct electricity in its molten state or when dissolved in water. In these forms, the ions are free to move and can carry an electric current. However, solid nickel chloride is an insulator and does not conduct electricity.
What metals will not dissolve in an aqueous solution containing nickel ions?
POSSIBLE ANSWER: nickel (Ni) EXPLANATION: all metals dissolve in water more or less and there is an equilibrium point at which the dissolving rate and the condensing rate are the same. If the solution already has enough nickel ions (in other words it is a saturated solution), then the solid nickel you put in will not dissolve.
When an acid reacts with a metal the liquid changes colour to green?
This depends on the metal; nickel chloride solution is green.
Is nickel ii clohirde a element?
No, nickel (II) chloride is a compound consisting of the elements nickel and chlorine.
What compound can undergo decomposition to produce nickel chloride and oxygen?
Nickel(II) chlorate (Ni(ClO3)2) can undergo decomposition to produce nickel chloride (NiCl2) and oxygen gas (O2).
What is the method to prepare nickel carbonate?
Prepare a solution of a nickel salt such as sulfate, nitrate, chloride, etc. This can be done by dissolving pieces of nickel in a strong acid mixture. Once you have the nickel salt, neutralize the solution and add excess baking soda. Then filter out the fine light green nickel carbonate.
What ions are present in an aqueous solution of NiCl₂?
Ni2+ + 2Cl- also OH- + H+ from water
Is nickel chloride an acid or base?
The solution of nickel chloride is acidic.
What are the examples of conductors?
Generally metals and ions (in solution) are good conductors of electricity. Eg. iron, copper, nickel, molten sodium chloride, aqueous sodium chloride etc.
What is the name of NiCl2?
Nickel (II) oxalate dihydrate; used in battery production.
How could you separate nickel carbonate from sodium carbonate?
One way to separate nickel carbonate from sodium carbonate is by utilizing differences in solubility. Nickel carbonate is insoluble in water, while sodium carbonate is soluble. By adding water to the mixture and filtering, the insoluble nickel carbonate can be separated from the soluble sodium carbonate.
Does nickel chloride conduct electricity?
Yes, nickel chloride can conduct electricity in its molten state or when dissolved in water. In these forms, the ions are free to move and can carry an electric current. However, solid nickel chloride is an insulator and does not conduct electricity.
What do you get when nickel carbonate reacts with dilute hydrochloric acid?
Nickel carbonate reacts with dilute hydrochloric acid to produce nickel chloride, carbon dioxide gas, and water.
What metals will not dissolve in an aqueous solution containing nickel ions?
POSSIBLE ANSWER: nickel (Ni) EXPLANATION: all metals dissolve in water more or less and there is an equilibrium point at which the dissolving rate and the condensing rate are the same. If the solution already has enough nickel ions (in other words it is a saturated solution), then the solid nickel you put in will not dissolve.
What is the correct name for the precipitate formed when mixing potassium carbonate and nickel(II) chloride?
silver chloride AgNO3(aq) + KCl(aq) --> AgCl(s) + KNO3(aq)
Can nickel reacts with hydrochloric acid?
Yes, nickel can react with hydrochloric acid to form nickel chloride and hydrogen gas. The reaction produces bubbles of hydrogen gas and the solution turns green due to the formation of nickel chloride.
How do you prepare 2 ppm solution of nickel nitrate?
To prepare a 2 ppm solution of nickel nitrate, you would dissolve 2 grams of nickel nitrate in enough water to make 1 liter of solution. This will result in a solution where there are 2 parts of nickel nitrate for every 1 million parts of water.
