What happens to copper sulphate when heated?
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
What two things happen when zinc is added to copper sulphate?
The Zinc will displace the copper. It will become Zinc Sulphate. The word equation will be Zinc + Copper Sulphate -----> Copper + Zinc Sulphate. Hope this helps!
What will be the colour of iron nail if it is added to cuso4?
Copper is deposited on the surface. This is an example of a single displacement reaction. Fe +CuSO4 -> Cu +FeSO4 the solution which started as blue (copper sulphate) becomes paler as the Copper ions, Cu2+ are replaced by ferrous ions, Fe2+ Iron is higher in the reactivity series than copper.
What happens when steel wool is added to copper sulphate?
Copper is deposed on the steel wool.
Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
Why does the water colour change to blue when copper sulphate was added?
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
What colour is pure water when anhydrous copper sulphate is added and is there a soild residue?
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
Why colour of copper sulphate solution changes to light green when iron filings are added?
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.
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 happens when sodium hydroxide is added to copper sulphate solution?
Nothing
What happens when copper sulphate is added to water?
Formation of a copper sulfate solution in water. This solution has a herbicide and fungicide effect.
What happens to copper sulphate when heated?
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
Does copper sulfate have a concentration?
A copper sulphate solution can have different concentrations depending on how much copper sulphate crystals have been added into the water. A typical 1 molar solution of copper sulphate would need 250g of CuSO4, mixed with 700ml of H2O, with 10ml of H2SO4 added with another 290ml of water.
What happens when excess hydroxide solution is added to copper II sulphate solution?
it fizzes up like poo and wee in ur body when people say ur sexy and ur nipples r great this is said when hydroxide solution is added to copper II sulphate solution
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
What would you see if you dropped a piece of magnesium ribbon into some copper sulphate solution in a test tube?
The ribbon starts to break up at the surface, a brown solid forms(copper metal), and the solution eventually becomes colourless (from losing copper ions)
