Hydrated copper sulphate is blue in color while anhydrous copper sulphate is white in color.CuSO4 is white, the pentahydrate crystal (CuSO4.5H2O) and the aquous solution (Cu2+(aq) ions) are royal blue. So the color comes from the hydration of Cu2+.
A displacement reaction takes place. Iron being a more reactive element than copper displaces copper from its compound. Ferrous Sulphate which is green in color and copper a reddish brown element are formed. So, blue color of copper sulphate fades away and the solution becomes light green. Copper is deposited on the grayish iron filings.
Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate
It turns blue because copper forms blue crystals when in solution. As soon as the water evaporates, there's nowhere for the copper to be in "solution", so it loses its colour. When water is added again, the crystals regain the "solution" state and turn blue!
Because in FeSO4, iron present in +2 oxidation state but the stable oxidation state is +3. The Fe(II) get oxidized into Fe(III) in ferrous sulfate solution that's why preparation of solution must necessary.
copper sulfate's chemical symbol is actually CuSO4 ... the symbol CuSO4-5H2O is copper sulfate pentahydrate... someone should edit the answer on CuSO4 copper sulfate

The white copper sulphate will become blue. This is because copper sulphate usually has 5 moles of H2O, but it has reached a temperature where all five moles will have detached themselves from the copper sulphate, so it will become anhydrous (without water) and white. Then, when water is added back to it, it returns to its original blue state.
Copper(II) sulphate is written like this because here II denotes the oxidation state of copper or in simple language, it denotes its valency.Copper sometimes shows +1 valency and sometimes +2.So to specify, its valency in a compound, the valency is written in brackets.

copper sulphate is soluble.dissolve the two in water whereby cuso4 dissolves.filter the mixture the put the filtrate in an evaporating dish to evaporate excess water.do not evaporate to dryness coz some water ir required for crystalization.
Copper sulphate can conduct electricity. However, this will only happen when it is in liquid or gaseous state but not in solid form.
The answer is, the Copper State's Symbol.
the symbol on the flag mean to remind us of the copper star state copper industry
Coarseness, stirring and temperature.
CuSO4.5H2O is hydrated copper sulphate ; a COMPOUND, not an element. However, it comntains the elements ;- 1 x Cu = 1 Copper 1 x S = 1 x Sulphur 4 x O =- 4 x Oxygen 5 X 2 = 10 x H = 10 Hydrogens 5 x 1 = 5 = 5 Oxygens. So hydrated copper sulphate comtains the elements , copper, sulphur, oxygen , hydrogen , and oxygen (water).
