What changes would you observe if you leave a copper sulphate in a room at 21 degrees for 2 days with a lid on the top?

The water from the solution evaporates. A decrease at mass and volume would also occur.

at stays the same

∙ 10y agoIf it is blue, it already has water of hydration. Water is readily absorbed from the atmosphere until saturation. In other words, you may and may not see a change. If it was pale blue, you most certainly would see it turn blue and weigh more (water of hydration), however, because 21C is not near hot enough to dry something, the question only depends on what can be drawn from the environment
I am englishhhhhh
The water will evaporate out leaving only the blue copper sulphate crystals in the dish.

∙ 14y agothere would be a decrease in volume and i think the colour would change
(not completely sure)

∙ 7y agoIf there is a lid on it, very little would change. If the lid is loose fitting there might be a little evaporation resulting in a more concentrated solution.

∙ 7y agoThe solution remain unchanged; only the anhydrous copper(II) sulfate is colorless.

Is copper sulphate a physical change or chemical?
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
Does copper sulphate undergo any physical or chemical changes during heating?
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.
Chemical reaction between calcium and copper sulphate?
calcium + copper sulphate = calcium sulphate + copper hydroxide
Iron nail dipped in copper sulphate solution?
When an iron nail is dipped in the solution of copper sulphate solution , after a while the solution changes into the colour of green becoming iron sulphate and a brown substance is found on the iron nail which is copper so we get to know that the displacement reaction is produced
Why does the color of copper sulphate change when an iron nail dipped in it?
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.
Why do you use copper sulphate?
A rather incomplete question. I could use copper sulphate for a number of reasons, for example as an electrolyte for copper plating, as a medium for growing impressive deep blue crystals, as a fungicide and so on. For fun, try dropping some iron filings into a fairly concentrated solution of copper sulphate and observe how the iron filings change to a copper colour and the solution changes to a green colour.
Is copper sulphate a physical change or chemical?
Copper sulfate is a substance, not a change. It can undergo physical and chemical changes.
What happens when an iron nail is dipped in copper sulphate solution?
A brown layer of copper gets deposited on iron nail. This change is due to a chemical reaction between copper sulphate and iron. Also the colour of the solution changes from blue to green due to the formation of iron sulphate. This reaction can be represented by the following equation: Copper sulphate + Iron = Iron sulphate + Copper solution (CuSO4) + (Fe) = (FeSO) + (Cu)
What happens when copper sulphate is dissolved in water?
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
Chemical reaction between calcium and copper sulphate?
calcium + copper sulphate = calcium sulphate + copper hydroxide
Does copper sulphate undergo any physical or chemical changes during heating?
On heating penta hydrated copper sulphate undergoes dehydration and changes colour from blue to white that means physical change but on heating it does not show a chemical change.
Why aqueous copper sulphate solution conduct electricity but solid copper sulphate does not?
aqueous copper sulphate having high conductive hydroxide ions were as no in solid Copper sulphate.
What do you get when you mix calcium and copper sulphate?
Calcium Sulphate + Copper
Is copper sulphate toxic?
no copper sulphate is not toxic it is flammable

What is observed when electric current is passed through copper sulphate?
its colour changes 2 blue
