Does hydrated copper sulphate increase the mass?
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
What effect would dissolving some copper sulphate crystals in the water have on its boiling point?
Adding copper sulphate crystals to water will raise the boiling point of the solution, as the dissolved particles disrupt the water molecules, making it harder for them to escape as vapor. This results in an increase in boiling point compared to pure water.
Is copper oxide soluble?
copper sulphate is soluble in water - take the reaction to form blue crystals (sulphuric acid + copper carbonate) - once the water is evaporated off blue crystals are left. And if the water is evaporated off still the crystals turn white! so it must be.
What gas or liquid if any would you get if you heated hydrated copper sulphate?
You would get water in the gas phase (steam). The word "hydrated" means that there are water molecules mixed in with the copper sulphate, and so when you heat it, you will turn that water into steam, freeing it. Because of the high melting point of ionic compounds like copper sulphate, it will not be affected by heating unless you go to extemely high temperatures.
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 would happen if you added copper sulphate to water at room temperature?
Copper sulfate is soluble in water and dissociated in ions (Cu2)+ and (SO4)2-.

What would be seen in a reaction between copper sulphate and magnesium?
magnesium+copper sulphate =no reaction

Is copper sulphate dissolves in water a physical or chemical change?
A physical change is different from a chemical change in two ways:1) In a physical change no new substances are made; in a chemical change new substances are made.2) A physical change can be easily reversed; a chemical change cannot be easily reversed.Dissolving copper sulphate in water does not produce a new substance. The copper sulphate solution is a mixture, not a pure substance.Also, by evaporating the water you can easily get the copper sulphate back again.So, dissolving copper sulphate is a physical change.Sometimes, though, when water is added to copper sulphate, it reacts with the water to form copper sulphate pentahydrate, which is a new compound. This would be a chemical change, but actually dissolving it is indeed a physical change only.See these sites for more information:http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/chem_react_2.shtmlhttp://www.chem4kids.com/files/matter_chemphys.html
What would happen if you put iron into a blue copper sulphate solution?
There would be copper deposited in the piece of iron and the solution would show a color change from pale blue to pale green.

What would happen if you leave copper sulphate in a dish with a lid on for 2 days at 21 degrees Celcius?
It will turn brown ish
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
What is the pool water dark after using copper sulphate?
the chlorine in the water oxidizes the copper causing an off color, if you used enough of each it would turn a greenish blue color.
