What else can I help you with?
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-.
When a solution of copper II chloride is added to a solution of potassium sulfide a double replacement reaction occurs and forms a black precipitate write an equation for the exchange of Ions?
CuCl2(aq) + K2S(aq) --> CuS(s) + 2KCl(aq) K and Cl are spectators so the net ionic would be: Cu2+(aq) + S2-(aq) --> CuS(s)
What is the oxidizing agent for Zn plus CuCl2--ZnCl2 plus Cu?
In the reaction Zn + CuCl2 → ZnCl2 + Cu, CuCl2 is the oxidizing agent because it accepts electrons from Zn, causing zinc to be oxidized and copper to be reduced.CuCl2 itself gets reduced to Cu.
What is the cucl2 called?
It is Copper chloride.It is written as Copper(ii) chloride.
Is cucl2 h2s cus 2hci a balanced equation?
CuCl2 + H2S --> CuS + 2HCl Yes, this is the balanced equation here.
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?
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 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.
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.
Why does copper reacts with sodium chloride?
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
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.
