blue
The formula unit for copper II sulfate is CuSO4.
Why does copper sulfate change its colour when water is added
blue
When calcium chloride is mixed with copper sulfate, a white precipitate of calcium sulfate forms due to the displacement reaction between calcium and copper ions. This reaction is a double displacement reaction in which calcium sulfate and copper chloride are formed.
When zinc granules are placed in a copper sulfate solution, zinc will undergo a displacement reaction with copper, displacing copper ions in the solution. This reaction will result in the formation of zinc sulfate solution and solid copper. The blue color of the copper sulfate solution will fade as the reaction proceeds.
Copper (II) sulfate is a salt that is green in color.
redd i guess lol[][][][][]
The anhydrous copper(II) sulfate is white, the pentahydrate is blue.Iron is gray.
Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.
Anhydrous copper sulfate solid is white. When it is added to water, it dissolves and the solution of aqueous copper sulfate becomes blue.
Hydrated copper sulfate appears as a bright blue color.
When water is added to anhydrous copper sulfate, it forms copper (II) sulfate pentahydrate, a blue crystalline solid. So, the color change observed is from white (anhydrous) to blue (pentahydrate) when water is added.
