When anhydrous copper sulfate (CuSO4) gets wet, it absorbs water and undergoes a chemical reaction to form hydrated copper sulfate (CuSO4·5H2O), which is commonly known as blue vitriol. This results in a color change from white to blue as the compound gains water molecules and becomes hydrated.

What happens to the temperature when anhydrous copper sulhate gets wet?
When anhydrous copper sulfate becomes wet, it undergoes an exothermic reaction as it absorbs water to form hydrated copper sulfate. This reaction releases heat, resulting in a temperature increase in the surrounding area.
What happens when an iron nail is dipped in copper sulphate solution?
When an iron nail is dipped in copper sulphate solution, a displacement reaction occurs where the iron displaces copper from the copper sulphate solution. This results in the formation of copper metal on the surface of the iron nail, causing the nail to become coated with a layer of copper.
Why does the copper sulphate powder turn blue and gets hot when add water to it?
When water is added to copper sulfate powder, it dissolves to form a solution. This dissolution is an exothermic process, meaning it releases heat, causing the solution to become warm. The blue color of the solution is due to the copper ions in the copper sulfate forming a blue complex with water molecules.
What happens to copper when it gets wet?
When copper gets wet, it can undergo a chemical reaction with the water and oxygen in the air, which forms a greenish layer known as patina. This patina acts as a protective coating, preventing further corrosion of the copper.
What happens to copper wire when heated?
When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
How copper sulphate diffuse in water?
copper sulphate gets hydrated in water and thus is diffusible.
What happens to the temperature when anhydrous copper sulhate gets wet?
When anhydrous copper sulfate becomes wet, it undergoes an exothermic reaction as it absorbs water to form hydrated copper sulfate. This reaction releases heat, resulting in a temperature increase in the surrounding area.
What happens when an iron nail is dipped in copper sulphate solution?
When an iron nail is dipped in copper sulphate solution, a displacement reaction occurs where the iron displaces copper from the copper sulphate solution. This results in the formation of copper metal on the surface of the iron nail, causing the nail to become coated with a layer of copper.
Why does the copper sulphate powder turn blue and gets hot when add water to it?
When water is added to copper sulfate powder, it dissolves to form a solution. This dissolution is an exothermic process, meaning it releases heat, causing the solution to become warm. The blue color of the solution is due to the copper ions in the copper sulfate forming a blue complex with water molecules.
Why does copper sulphate turn green when iron is added?
When iron is added to copper sulfate, a displacement reaction occurs where the iron displaces the copper in the compound forming iron sulfate and elemental copper. The green color seen is from the formation of copper metal, leaving behind iron sulfate which is colorless.
What happens to copper when it gets wet?
When copper gets wet, it can undergo a chemical reaction with the water and oxygen in the air, which forms a greenish layer known as patina. This patina acts as a protective coating, preventing further corrosion of the copper.
What happens to copper wire when heated?
When copper wire is heated, it expands due to thermal expansion. As it gets hotter, the electrons in the copper atoms move more freely, increasing electrical resistance. Excessive heating can cause the copper wire to melt and ultimately vaporize.
What happens when copper is heate?
The brown colored element, copper on heating in air forms copper oxide which in black in color. 2Cu(s) +O2(g) gives rise to 2CuO(s)
Why will iron displace copper from aqueous solutions of copper salts?
Iron is more reactive than copper, so when iron is added to a solution of copper salt, iron will displace copper by reducing it from its cationic form (Cu2+) to its elemental form (Cu). This is due to the difference in the reactivity series of metals, with iron being higher in the series than copper.

Sulphate and other chemicals!
When an iron nail is placed into a solution of copper sulfate what happens?
In this case, copper ions from the copper sulfate solution will react with the iron in the nail through a redox reaction. The iron will gradually dissolve into the solution, while copper ions will deposit on the surface of the nail, forming a layer of copper on the nail.
