Ruth would be able to see that the copper sulfate crystals had dissolved in the water by observing if the crystals disappeared completely and the water turned into a clear blue solution. This indicates that the crystals have broken down and mixed evenly with the water, creating a homogeneous solution.
What else can I help you with?
how does Ruth know that some of the copper sulphate crystals had dissolved in the water?
Ruth would know that some of the copper sulphate crystals had dissolved in the water by observing if the water changed color to blue, which indicates that the copper sulphate dissolved. Additionally, she could check if there are fewer crystals at the bottom of the container, as they would have dissolved into the water. Ruth can also test by inserting a clean spoon and checking if any more crystals can stick to it, indicating that some have dissolved.
What color is copper sulphate?
Blue...but you could just google this in google images...??
Can copper displace iron from iron sulphate solution?
In the normal conditions, it is not possible as iron is more reactive than copper. However, it is possible in an an electrolytic cell where an opposite electric potential is applied opposite to the normal potential so that the reaction could take in the opposite direction. In this case copper would be able to replace iron from iron sulphate.
What compound is a light green powder?
I think it could be Barium sulphate if its a powder
Is copper sulfur a pure substance or a mixture?
There is no substance called "copper sulphur". You could have a mixture of copper and sulphur, though. But there are compounds (pure substances) of copper and sulphur as well. They include copper I and copper II sulphide (Cu2S and CuS). Another, very common compound is copper sulphate, CuSO4

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.

What is formed when solid copper sulphate is mixed with water?
Take a cupful of water in a beaker and add few drops of dilute sulphuric acid. Heat water. When it starts boiling add copper sulphate powder slowly while stirring continuously. Continue adding copper sulphate powder till no more powder can be dissolved. Filter the solution. Allow it to cool. Do not disturb the solution after some time. We can see the crystals of copper sulphate. If we do not see any crystals, wait for some more time. Your copper sulphate crystal is ready. By: darani.a
Is copper product or reactant?
For copper, it is an element. It could be both reactant and product. While purifying copper will be the product. But copper would be the reactant in case of preparing hydrogen or copper sulphate salts.
Could separate iron filings from copper sulphate and copper oxide with a magnet?
Yes, a magnet would remove the iron filings without attracting the copper salts, copper salts are not magnetic.

What makes copper ii sulphate?
Copper(II) sulfate [also called - cupric sulfate or copper sulphate] has the chemical formula CuSO4. That means it is made of Copper (Cu), Sulphur (S) and Oxygen (O) It is also found with adsorbed water (hydrated) which means that you could ad Hydrogen (H) to the mix.
How could you get the salt crystals back once you had dissolved them in water?
You will have to let the water evaporate by drying in the air or heating slightly.
What compound is a light green powder?
I think it could be Barium sulphate if its a powder

Is it possible to store CuSO4 solution in Zn container?
No, storing a CuSO4 solution in a Zn container is not advisable as it can lead to a redox reaction where the zinc will react with the copper in the solution. This could result in the formation of copper metal and zinc sulfate, potentially damaging the container and affecting the solution's integrity. It is recommended to store CuSO4 solutions in glass or plastic containers.
