Hydrated Copper Sulphate is CuSO4.5H2O and Anhydrous copper sulphate is just
CuSO4. Therefore, hydrated copper sulphate has extra mass due to water molecules
present in it.

What happens when add water to copper sulphate?
An exothermic reaction occurs (this is when heat is produced). There's a link between the mass of copper sulphate and the temperature rise of the water.
If you heat copper why does its mass increase?
Its mass increases because it oxidises. ie Oxygen is gained. This forms copper oxide.
Why does copper's mass increase when heated?
Any object will increase in mass, if you increase its energy (E = mc2). The effect is insignificant under normal circumstances.Apart from that, the mass of copper will not inrease. It will burn at some point and the reslulting compounds will weigh more.
How can you tell if a hydrate has turned into an anhydrous salt?
1- on heating the mass of material becomes reduced due to elimination of water molecules. 2- in some cases the colour change may be observed as penta hydrated copper sulphate is blue while anhydrous copper sulphate is a white solid.
Chemical name of Plaster of paris?
Calcium sulphate hemihydrate, CaSO4.1/2H2O
Does the mass of water increase when you add copper sulfate?
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
Does copper sulphate dissolve better in cold water or in warm water?
Copper Sulphate will dissolve better in warmer water, it will dissolve both faster and it will be possible do dissolve a greater mass of the Copper Sulphate.

Why was it necessary to weigh the iron filings accurately though the mass of copper sulphate taken was only approximate?
it is because iron is solid and can easily sublimes in aqueous copper sulphate
Does the mass stay the same in a redox reaction between iron copper sulphate?
If you are considering just the mass of the solid then no, only the amount of moles reacted for each compound will be the same. Since the molecular weight for Copper (ii) is higher than iron (ii) the mass of the solid (Cu) will increase slightly.
What is the molar mass of copperII hydroxide?
There are 2 forms of Copper(II) Sulphate, each with a different molar mass. * Copper(II) Sulphate Pentahydrate (CuSO4.5H20) This is the more common, blue, crystalline solid. it has a molar mass of: 249.7g mol-1 * Anhydrous Copper(II) Sulphate (CuSO4) This is less common to come across, it is a white powdery solid,and can be obtained by heating the pentahydrated form. Molar mass: 159.6g mol-1
When you heat up copper does the mass increase?
No.
What is the largest mass of copper sulphate which can be dissolved in 50g of water at 60 degrees centigrade?
20g I think

How do you get the weight of copper sulphate?
To get the molar mass of copper sulfate (CuSO4) Add the molar masses (atomic weight) of each element of the compound together, this will give you the molar mass of the compound. In This case 159.6086 g/mol
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.
