The Colour Of Copper Sulphate Solution Is

Iron nails were dipped in an aqueous solution of copper soleplate.

The colour of copper sulphate solution is.

Copper ii sulfate also known as copper sulphate are the inorganic compounds with the chemical formula cu so 4 h 2 o x where x can range from 0 to 5 the pentahydrate x 5 is the most common form. Blue colour of the copper sulphate solution changes into green colour then iron nail acquires a brownish look. The colour of anhydrous copper sulphatecrystals are white they can be used to detect the presence of water they turn blue if water is present forming hydrated copper sulphate the water solution. The following chemical reaction takes place in this activity.

Blue is the solution s color when blue cuso4 5h2o copper ii sulfate pentahydrate is dissolved the solution turns blue. F e c u s o 4 f e s o 4 c u in this reaction iron displaces copper from c u s o 4 solution. This is because that iron is more reactive than copper. When the copper sulfate is heated up it quickly turns to a pure white color that has no hint of blue in it.

Asked aug 8 2019 in class x science by priya12 12 631 points chemical reactions and equations. When white cuso4 anhydrous copper ii sulfate is dissolved the. It is sometimes called blue copper for this reason. Older names for this compound include blue vitriol bluestone vitriol of copper and roman vitriol.

The pentahydrate cuso 4 5h 2 o the most commonly encountered salt is bright blue. The colour of the solution is due to the wavelengths of light that are not absorbed as white light passes through the solution. Now if we dilute the original copper sulfate solution by adding more water the blue colour becomes less intense it is a lighter blue colour because the solution is not absorbing as much of the other wavelengths as before.
