When zinc metal is placed into a solution of copper sulphate a pinky brown metal is formed but when a piece of silver metal is placed into another solution of copper sulphate no change is observed Why?
Silver is lower in the reactivity series than Zinc and therfore cannot displace the Sulphate from the Zinc. But on the other hand zinc is higher than copper, and when displacing the sulphate from the copper it changes colour due to the reaction. Reactivity series(metals): Potassium Sodium Lithium Calcium Magnesium Aluminium Zinc Iron Tin Lead Copper Silver Gold Platinum
What is the product of iron and copper II sulfate?
iron + copper sulphate ''goes to'' iron sulphate + copper
What happens to the particles of copper sulphate and iron?
A displacement reaction takes place. Iron being a more reactive element than copper displaces copper from its compound. Ferrous Sulphate which is green in color and copper a reddish brown element are formed. So, blue color of copper sulphate fades away and the solution becomes light green. Copper is deposited on the grayish iron filings.
Why copper can conduct elevtricity when solid or liquid but copperII sulphate can only conduct electricity if molten or aqueous?
Because in solution the ions Cu2+ and (SO4)2- are formed. In copper (metal) electrons can move free.
What is formed when solid copper sulphate is mixed with water?
Take a cupful of water in a beaker and add few drops of dilute sulphuric acid. Heat water. When it starts boiling add copper sulphate powder slowly while stirring continuously. Continue adding copper sulphate powder till no more powder can be dissolved. Filter the solution. Allow it to cool. Do not disturb the solution after some time. We can see the crystals of copper sulphate. If we do not see any crystals, wait for some more time. Your copper sulphate crystal is ready. By: darani.a
How does copper and zinc sulphate react together?
zinc is more reactive than copper hence it displaces the copper in copper sulphate solution to become zinc sulphate and copper metal is formed
What happens when ammonia is added to copper sulfate?
When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
Why does solid copper sulphate conduct electricity when dissolved in water?
Because in solution the ions Cu2+ and (SO4)2- are formed.
What happens when you add powdered zinc to a mixture of copper sulphate?
The solution becomes a paler blue and a brownish solid is formed
What happens when ammonia solution is added to copper sulphate?
A precipitate is formed which has a light blue colour. After shaking, the precipitate re-dissolves forming a dark blue solution.
What salt is formed when copper reacts with sulphuric acid?
Copper sulphate CuSO4
What the are products formed when copper reacts with sulfuric acid?
Copper(II)sulphate and hydrogen.
What is the chemical equation for when iron is added to copper sulphate iron sulphate is formed and copper falls to the bottom?
Fe = CuSO4 ----> FeSO4 + Cu

What do hydrogen sulphide and copper sulphate form when mixed together?
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
Why can't you evaporate copper sulphate solution to separate copper sulphate crystals?
It is because the copper suphate chloride has a pH of 2334. This means crystals cannot be formed but instead hydrochloric methanical acid is formed. hydrochloric methanical acid is VERY harmful to us so kids: DON'T TRY THIS EXPERIMENT AT HOME!!thank you,love from Mr Smelma Pits
What is the product of iron and copper II sulfate?
iron + copper sulphate ''goes to'' iron sulphate + copper
