when copper is put with water it turns green like the statue of liberty it is actually a browny bronze colour but when water and other chemicals react with it, it chages colour to a green colour
Copper does not corrode in water, but only at negligible rates, about 0.4 mm in over two centuries.This is especially true for copper alloys.
the water then appears coulerless
it would explode
It turns into a white powder and when water is then again added to the deydrated copper sulphate it turns back to its original colour
Reaction of a metal oxide with water produces a metal hydroxide, which is a strong base
No, it dosent. If a base can be dissolved in water, its corresponding metal oxide must be able to be dissolved in water. So you see copper hydroxide is solid, which means it can't be dissolved in water. So copper oxide can't react or be dissolved in water to form copper hydroxide.
Copper metal "dissolves" in nitric acid (HNO3). Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO2 gas in the process; the copper (II) ion then binds to six water molecules.
When water is added to a metal namely SnI4, nothing will happen. Both water and metal will remain at its normal state.
Copper sulfate is soluble in water and dissociated in ions (Cu2)+ and (SO4)2-.
Anhydrous copper(II) sulphate is white. When added to water, it forms a solution of CuSO4(aq) which is blue because of the Cu2+ ion, which is itself a transition metal ion.
Why does copper sulfate change its colour when water is added
Copper is a metal element. It does not dissolve in water.
Copper
The colour of silver metal in water is whiteThe colour of copper nitrate in water is blue (due to the Cu++ ion).
Salt water affects copper by causing corrosion. The non-oxidizing acids in the salt water break down the copper metal and in turn, the metal loses its color and begins to rust.
it depends what metal it is, if it is a reactive metal like potassium or sodium it will effervesce (bubble) and create a metal hydroxide and hydrogen. if it is a less reactive metal it will create a metal oxide and hydrogen (zinc, etc)
oxidation
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!!!!!!!!!!!
