it sucks
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
When copper metal is placed in a solution of silver nitrate, a reddish-brown solid called copper(I) oxide is formed on the surface of the copper. This occurs due to a single displacement reaction where copper displaces silver from the silver nitrate solution.
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!
The state symbol of copper nitrate solution would be (aq), indicating that it is dissolved in water.
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.
When heated blue copper sulphate solution does evaporate!!!! The result is BLUE copper sulphate crystals of the penta-hydrate (CuSO4.5H2O). If you continue to heat these blue crystals, they will turn white in colour as you drive off the water of hydration. CuSO4.5H2O(s)(Blue) ==heat==> CuSO4(s)(white) + 5H2O(g) The analogy of hydration is like holding a ball in your hand. Your hand is the copper sulphate, and the ball is the water. Open your hand (heat) and the ball falls away(water is released). Your hand and the ball remain separate objects (NOT combined). Similarly the copper sulphate and the water remain separate molecules (NOT combined). It's just that the one is held (in the crystal lattice), by the other.,
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 can conduct electricity. However, this will only happen when it is in liquid or gaseous state but not in solid form.

not pure iron... But you can provide a covering over iron to make it look like copper by just dipping it into copper sulphate solution .. Because Iron is more reactive than Copper ... it will displace it in the solution .. the color of solution will change so as the color of iron!
The answer is, the Copper State's Symbol.
