will the percent water loss be more or less if you heat the salt a little too much and it decomposed and vaporized

Test for presence of water in anhydrous copper sulphate?
In the presence of water the white anhydrous copper sulfate become blue.
What is meant by the word anhydrous when applied to a chemical?
Anhydrous simply means 'without water'. The opposite is a hydrated substance, in which salt crystals contain water as an integral part of the crystal. For example, anhydrous cobalt(II) chloride, CoCl2, is a blue powder. Add water and you form cobalt(II) chloride hexahydrate, CoCl2.6H2O, which is a pink colour. Anhydrous cobalt chloride can be used to test for the presence of water because of this dramatic colour change. In addition, hydrated copper(II) sulfate, CuSO4.5H2O, forms bright blue crystals. Heating them drives off the water of crystallisation and anhydrous CuSO4, a grey/white powder, is formed. Adding water will reform a blue solution of the hydrated salt.
What is the color of copper sulphate?
Copper sulfate itself is white/colorless when anhydrous. However, it's hygroscopic and the pentahydrate (the usual form) is blue... in fact, it's just about the same color as the sidebar over to the left there.
Solids tends to be hydrated in the presence of water?
ionic!!!
What is anhydrous?
A hydrated crystal in one that has water molecules trapped inside the crystal structure of some other compound, typically an ionic compound. The water is chemically combined with a substance in such a way that it can be removed, as by heating, without substantially changing the chemical composition of the substance. As a good example, copper sulfate is a commonly hydrated crystal. To show that it is hydrated, you would write CuSO4 . 5H2O. By putting a dot in between the two, it indicates that they are waters of hydration, not really part of the compound (you can remove them by heating the crystals). You can see in this case, there are 5 water molecules for each CuSO4.
When added to copper sulphate what colour is anhydrous copper sulphate?
anhydrous copper sulphate is white. when water is added it turns blue, in essence it can be used to detect the presence of water. hope this helps!!!!!!!!!!!
What hydrocarbon is obtained when Na metal react with ethyl bromide in presence of anhydrous ether?
By Wurtz reaction Butane is formed.
Why anhydrous copper II chloride is used to test for the presence of water?
it condenses as the black papers lighten up like a dynamite
How does water rust a nail?
In the presence of oxygen a reaction occur (oxidation) and the hydrated iron oxide is produced.
Why unhydrated alcl3 is covalent in nature but hydrated alcl3 becomes ionic in nature?
In the presence of H2O, Al2Cl6 dissociates into hydrated Al3+ and Cl- ions due to high heat of hydration of these ions
The weakest symbiotic attachment in which one species simply lives better in the presence of another species that is relatively unaffected is called?
mutualism
What substance does Benedict's solution test for?
Benedict's reagent is used as a test for the presence of all monosaccharides, and generally also reducing sugars. These include glucose, galactose, mannose, lactose and maltose. Even more generally, Benedict's test will detect the presence of aldehydes (except aromatic ones), and alpha-hydroxy-ketones, including those that occur in certain ketoses. - wikipedia
