Not necessarily. They might be blue, green, or essentially white depending on how many waters of hydration are associated with the copper (II) ion. It's very easy to see this if you just take some copper (II) sulfate pentahydrate (blue vitriol) in a test tube and heat it; as the waters of hydration are driven off, the crystals turn white (some people call it a very light green; it looks white to me). When the crystals are allowed to cool they will absorb water from the air and eventually turn blue again. Aqueous solutions of copper (II) compounds are blue, as far as I know; at least I can't think of any counterexamples.

Why do copper compounds usually appear colourless although copper is a transition element?
Sorry, but most copper compounds are some shade of blueor green, not colorless at all!
Why is colour of copper sulphate blue?
The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
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.
What is the charge for copper hydroxide?
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.
Why do compounds of zinc white but compounds of copper have color?
Zinc compounds are white because its d sub-shell is all full so transfer of electrons cannot occur.Check it out : 1s2 2s2 2p6 3s2 3p6 3d10 4s2
What does crystallized copper sulfate look like?
Greenish - blue, like (almost) all copper compounds.

The colour of Copper sulphate is blue because Copper ions absorb light in all frequencies except blue which is reflected instead.
What flame colour does copper chloride give?
Flame colours depend on just the metal ion. All copper compounds give the same colour, green.
Why do you filter blue copper sulphate solution?
to remove all impurities

Is copper an elemnt or compound?
Copper is an element because it cannot be broken down past it's state of being copper. All compounds can pretty much be broken apart or separated, but elements are unable to be separated. Therefore, copper is an element.
What is the charge for copper hydroxide?
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.

Why is Lincoln 1943 penny worth more?
The 1943 penny was not made with copper, like all other years. Copper was funneled to the War Department so the 1943 penny was made from steel and other compounds.
Does copper ll chloride conduct electricity in the aqueous state?
Copper II chloride (CuCl2) is an ionic compound because copper is a metal and chloride is a non-metal. Like all ionic compounds in aqueous solutions (i.e., dissolved in water), it conducts electricity.
