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+.

How do you prepare cupric chloride solution?
CuO + 2 HCl -> CuCl2 + H2O Please see the link.
The blue color in the copper sulfate solution is due to the presence of what ion?
Since copper (I) chloride has only limited solubility in water I will assume you mean copper (II) chloride, CuCl2. Then the ions will be Cu2+ and Cl-.
What is the oxidizing agent for Zn plus CuCl2--ZnCl2 plus Cu?
CuCl2
Is cucl2 h2s cus 2hci a balanced equation?
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
What does CUCL2 stand for?
Copper dichloride
Is cucl2 aqueous?
Under normal conditions CuCl2 can exist in either a solid state or in aqueous solution.
What is the flame color of Cucl2?
green
What color does CuCl2 burn?
CuCl2 does NOT burn per se. However, when CuCl2 is dissovled in water in to Cu^2+ ions and Cl^- ions. Pass a ni-chrome or platinum wire through the solution, and then pass the wire through a Bunsen Burner flame. The flame colour will becomes a beautiful Blue/Green colour.
What is the molarity of a solution prepared by dissolving 20.00g CaCl2 in enough water to make 1.00L of solution?
20.2 g of CuCl2 = .1502 mol CuCl2 M=mol/L M=.1502 mol/L
Why does copper reacts with sodium chloride?
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
What is the equation when zinc metal is added to a solution of copper II chloride?
The chemical equation for the reaction that occurs when zinc metal is added to a solution of copper II chloride is: Zn + CuCl2 -> Cu + ZnCl2.
How do you prepare cupric chloride solution?
CuO + 2 HCl -> CuCl2 + H2O Please see the link.
What is the formula name of CuNH4Cl2?
As gaseous ammonia with solid coppersulfate: 2NH3(g) + CuSO4(s) --> Cu(NH3)2SO4(s) With water: [Cu(NH3)2]2+ complex-ions with SO42- ions in aquous solution (deep blue color)
What is the colour change when copper carbonate and sulphuric acid?
Copper carbonate powder is a bluish green. When colorless sulphuric acid is added, the resulting solution has a slightly diluted color and a bunch of bubbles appear, making the color a lighter bluish green. However, when this solution is introduced to a flame (which would ordinarily be yellow), the flame burns green.
Which ion is responsible for the colour that is observed in the CuCl2 solution?
CuCl2(s) = Cu^2_(aq) + + 2Cl^-(aq) In solution the chloride anions )Cl^-) are colourless ; see also dissolved common salt (NaCl) So it must be the copper cations (Cu^2+) that gives the colour blue.
To what volume should you dilute 131ml of an 7.95M CuCl2 solution so that 50.5ml of the diluted solution contains 5.8g CuCl2?
First multiply .131ml and 7.95M to get the moles of Cucl2. (You will need this later) Then find the moles per 49.5ml diluted solution. (6.1g divided my molar mass) Then set both equal to each other Original mol/X = Diluted mol/49.5ml and solve for X This should work
Why does CuCO3 plus HCl turn green?
Cu(CO3) + 2HCl --> CuCl2 + H2O + CO2 CuCl2 product, when dry is a yellow/brown powder. However, when wet it forms a co-ordination complex with the water in the solution: CuCl2.2H2O --> Cu(Cl)2(H2O)2 The electronic structure of transition metals and ligands cause visible colours. In this case the solution is blue/green in colour. If you dry the solution down you will get a blue/green powder. Drying further in a dessicator will give the yellow/brown anhydrous CuCl2.
