Best Answer

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+.

Yes, CuCl2 (copper (II) chloride) is soluble in water and forms an aqueous solution.


What is the flame color of Cucl2?

The flame color of CuCl2 is blue-green. This color is often observed when copper compounds are heated in a flame.


What is observed when the NaSO3 solution is added to the CuCl2 solution?

When NaSO3 is added to CuCl2 solution, a white precipitate of CuSO3 forms. Copper(II) sulfite is insoluble in water, causing it to precipitate out of the solution.


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


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.


Is cucl2 awhat kind of base is cucl2?

Copper(II) chloride (CuCl2) is not a base; it is a salt that is composed of copper(II) cations and chloride anions. It is an ionic compound that can dissociate in solution to form copper ions and chloride ions.


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, calculate the moles of CuCl2 in 5.8g. Then, use the molarity of CuCl2 to find the initial moles of CuCl2 in 131ml of the original solution. Finally, calculate the volume of the diluted solution needed for 50.5ml to contain the moles of CuCl2 obtained.


Why does CuCO3 plus HCl turn green?

When copper(II) carbonate (CuCO3) reacts with hydrochloric acid (HCl), copper(II) chloride (CuCl2) and carbon dioxide gas (CO2) are produced. The green color observed is due to the formation of copper(II) chloride, which has a greenish color.


What is the equation when zinc metal is added to a solution of copper II chloride?

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)


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.
