To find the mass of anhydrous copper(II) sulfate obtained:
- Calculate the molar mass of each compound: CuSO4·5H2O (pentahydrate) and CuSO4 (anhydrous).
- Use the molar ratio between CuSO4 and CuSO4·5H2O to find the amount of anhydrous CuSO4.
- Convert the amount to mass using the molar mass of CuSO4.
The mass of anhydrous CuSO4 will be less than the initial 125g due to the loss of water upon heating.

What colour does water change anhydrous copper sulfate?
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.
What happens if Copper Sulphate penta-hydrate is heated?
When copper sulfate pentahydrate is heated, it undergoes a dehydration reaction where the water molecules are released, leaving behind anhydrous copper sulfate. This process is reversible, and when anhydrous copper sulfate is exposed to moisture, it will reabsorb water and form copper sulfate pentahydrate again.
How many grams of copper(II) sulfate pentahydrate would you need to measure in order to have 10.0 grams of anhydrous copper (II) sulfate?
To calculate this, you would need to consider the molar masses of copper(II) sulfate pentahydrate and anhydrous copper(II) sulfate. Copper(II) sulfate pentahydrate has a molar mass that includes water molecules, so you need to determine the molar mass difference between the two compounds. Using this information, you can calculate the amount of copper(II) sulfate pentahydrate needed to obtain 10.0 grams of anhydrous copper(II) sulfate.
Heating copper II sulfate pentahydrate?
To heat copper II sulfate pentahydrate, you would need to apply heat gradually to remove the water molecules bound in the crystal structure. As you heat it, the pentahydrate will lose its water molecules and eventually transform into anhydrous copper II sulfate, which is a white powder. It's essential to heat it gently to prevent decomposition or spattering.
How do you remove colour from copper sulphate using anhydrous?
To remove color from copper sulfate using anhydrous, you can mix the anhydrous copper sulfate with a small amount of water to dissolve the compound. Then filter the solution to separate the insoluble impurities. Finally, evaporate the water to obtain anhydrous copper sulfate in its white color form.
Describe the appearance and odor of the liquid obtained by heating copper 11 sulfate pentahydrate?
When copper II sulfate pentahydrate is heated, it decomposes to form anhydrous copper II sulfate. The appearance of the resulting liquid is a clear, colorless solution. It does not have a specific odor.
Why colour of CuSO4 crystals changes on heating?
The blue copper sulfate pentahydrate loss by heating water and become an anhydrous white sulfate.
What kind of chemical reaction do you get when you heat copper sulfate pentahydrate?
Heating copper sulfate pentahydrate leads to a dehydration reaction, where water molecules are removed from the compound. This results in the formation of anhydrous copper sulfate.
What colour does water change anhydrous copper sulfate?
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.
What is the balanced equation when copper ll sulfate pentahydrate is heated?
The balanced equation for the heating of copper(II) sulfate pentahydrate (CuSO4•5H2O) is: CuSO4•5H2O(s) -> CuSO4(s) + 5H2O(g). This reaction decomposes the pentahydrate compound into anhydrous copper(II) sulfate and water vapor.
What happens if Copper Sulphate penta-hydrate is heated?
When copper sulfate pentahydrate is heated, it undergoes a dehydration reaction where the water molecules are released, leaving behind anhydrous copper sulfate. This process is reversible, and when anhydrous copper sulfate is exposed to moisture, it will reabsorb water and form copper sulfate pentahydrate again.
How many grams of copper(II) sulfate pentahydrate would you need to measure in order to have 10.0 grams of anhydrous copper (II) sulfate?
To calculate this, you would need to consider the molar masses of copper(II) sulfate pentahydrate and anhydrous copper(II) sulfate. Copper(II) sulfate pentahydrate has a molar mass that includes water molecules, so you need to determine the molar mass difference between the two compounds. Using this information, you can calculate the amount of copper(II) sulfate pentahydrate needed to obtain 10.0 grams of anhydrous copper(II) sulfate.
Heating copper II sulfate pentahydrate?
To heat copper II sulfate pentahydrate, you would need to apply heat gradually to remove the water molecules bound in the crystal structure. As you heat it, the pentahydrate will lose its water molecules and eventually transform into anhydrous copper II sulfate, which is a white powder. It's essential to heat it gently to prevent decomposition or spattering.
What will happen if heat crystals of CuSO4 pentahydrate in a test tube and note the water given off allow to cool and compare the color of anhydrous CuSO4 with original crystals?
Heating crystals of CuSO4 pentahydrate in a test tube will cause the water molecules trapped in the crystal lattice to evaporate, leaving behind anhydrous CuSO4 crystals. The color change observed will be from blue (for the hydrated form) to white (for the anhydrous form).
How do you remove colour from copper sulphate using anhydrous?
To remove color from copper sulfate using anhydrous, you can mix the anhydrous copper sulfate with a small amount of water to dissolve the compound. Then filter the solution to separate the insoluble impurities. Finally, evaporate the water to obtain anhydrous copper sulfate in its white color form.
- What would happen to the anhydrous cupric sulfate if you added water to it?
Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.
Is heating copper sulfate pentahydrate a chemical reaction?
Heating copper sulfate pentahydrate causes a physical change where water is removed, leaving anhydrous copper sulfate behind. This is not a chemical reaction, as the chemical makeup of the substance remains the same before and after heating.
