Blue, because the copper cations become hydrated and the hydrated ions have a blue color.
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
White copper sulfate is anhydrous, meaning it does not contain water molecules. When water is added to white copper sulfate, it forms a hydrate compound called blue copper sulfate pentahydrate. The water molecules coordinate with the copper ions, causing the compound to change color from white to blue.
When water is added to white copper sulfate (CuSO4), it dissolves and forms a blue-colored solution. This reaction is reversible, as the blue color disappears when the water evaporates and the white copper sulfate crystals are left behind.
When water is added to anhydrous copper (II) sulfate, it will undergo an exothermic reaction where the compound absorbs water molecules to form hydrated copper (II) sulfate. The anhydrous copper (II) sulfate changes color from white to blue as it forms the hydrate.
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/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!!!!!!!!!!!
When copper sulfate is added to sodium hydroxide, a blue precipitate of copper hydroxide is formed. The color change observed is from the initial blue color of copper sulfate to the blue precipitate of copper hydroxide.
The copper sulfate reacts with the water, creating a new substance with a different color.
Copper sulphate's colour is blue.
Blue...but you could just google this in google images...??
Hydrous copper sulphate, when heated, turns into anhydrous copper sulphate and changes its color from blue to white. The blue color comes from the water molecules bound to the copper sulphate crystals, and when heated, these water molecules are removed, resulting in a color change.
Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.
the copper sulphate i used at room temperature was blue.
The copper sulphate will likely give the pasta a blue or green hue, while the sodium chloride (salt) will not significantly alter its color. The overall color may appear bluish-green due to the copper sulphate.
When you add copper sulphate solution to iron wool. The iron wool turns copper in color and the copper sulphate solution turns pale blue as the iron displaces the copper from the copper sulphate solution forming iron sulfate.
When blue copper sulphate is heated, it loses water molecules and converts to anhydrous copper sulfate, which is white in color. The blue color of copper sulfate is due to the presence of water molecules in its crystal structure.
When copper sulfate is heated, it undergoes thermal decomposition, turning into copper oxide, sulfur dioxide gas, and oxygen gas. The color of the compound changes from blue to black as the heating process progresses.
