Copper salts generally absorbs the light of a wavelength of 580-630 nm..By looking at the colour you will see that directly opposite the colour orange is the blue green...that's why most of the copper salts have blue colour

What color is the flame when you burn copper II chloride?
A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
The sky's blue color is caused by?
The sky's blue color is caused by the refraction of light in the water vapor in the air, and blue is simply the color we see most.
Is cupric sulfate blue?
Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.
Deep blue minerals associated with copper deposits?
Most common would be azurite and clinoclase.
What is the reaction between iron and copper nitrate?
We have just done a lab about single displacement reactions. Most students got a reaction in which the blue solution of copper (II) nitrate turned black/bronze color. Fe is above Cu in terms of reactivity series. Therefore, it will displace copper.
What is the element most of its soluble salts are blue?
You think probable to copper.
What effect does copper by products have on the environment?
Copper salts are toxic to most living things.
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.
Why copper is colorless but gold has color?
Whereas most pure metals are gray or silvery white, but gold is yellow. This color is determined by the density of loosely bound (valence) electrons; those electrons oscillate as a collective "plasma" medium described in terms of a quasiparticle calledplasmon. In the other hand copper compounds are commonly encountered as salts of Cu2+, which often impart blue or green colors. However Cu+ ion has no color.
What colours is copper sulphate?
Pure copper sulfate is actually a white-grayish -green powder. When water is added it makes the pentahydrate CuSO4.5H2O which is quite a deep blue in color which is what most people would answer and think of as the color.
What color is the flame when you burn copper II chloride?

What causes the color in the solution after the reaction between silver nitrate and copper is complete?
It would be blue, or turquoiseincidentally the color of turqouise stone is also derived from copper, in fact most copper solution in inorganic chem are blue. This is owing to copper being commonly found in a (II) oxidation state and octahedral coordination geometry resulting in a similar crystal field spliting energy.
What is the color of most nickel containing salts?
white silvery
Pieces of metal are heated by varying amounts in a flame The hottest of the pieces will be the one that sHow is most prominently which color?
copper white
Do soluble salts show any colour in aqueous state?
Most of them don't, but some do give color in aquous solution, eg. copper(II) ions are blue, iron(III) = ferric ions are pale green, cobalt rose colored, KMnO4 solution is very dark purple (potassium permanganate)
What is the most liked color in the US?
