What happens when copper sulphate react with potassium cyanide?

There's nothing to drive the reaction, since all the possible combinations are soluble. Before, you would have copper, sodium, chloride and sulfate ions in solution; after, you would have the same thing. It's not really a reaction if nothing happens.

∙ 13y agoYes, yes it does. precipitation reaction occurs, where Potassium Sulfide is the solid/precipitate and potassium and sulfate are the spectator ions.
Balanced equation below!
CuSO4(Aq) + K2S(Aq) ------> CuS(S) + K2SO4(Aq)
Balanced net ionic equation below!
Cu2+(Aq) + SO42−(Aq) + K+(Aq) + S2−(Aq) ----------> CuS + K+(Aq) + S2−(Aq)
Cu2+(Aq) + S2-(Aq) -----------> CuS(S)

Wiki User
∙ 13y agoIt produces Copper(I) cyanide, Cyanogen and Sodium sulfate :
2 CuSO4 + 4 NaCN ----> 2 CuCN + C2N2 + 2 Na2SO4

What is the composition of fehling's solution?
Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate, Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
Add an excess of potassium iodide to copper sulphate solution how much is excess?

What happens on placing iron nails in a beaker containing Copper Sulphate?
when iron nails are kept in a beaker containing copper sulphate displacement reaction takes place.Iron is more reactive than copper so it displaces copper from the copper sulphate solution.Thus it becomes iron sulphate+copper
Chemical reaction between calcium and copper sulphate?
calcium + copper sulphate = calcium sulphate + copper hydroxide
Why does the color of copper sulphate change when an iron nail dipped in it?
When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour.Therefore, the blue colour of copper sulphate solution fades and green colour appears.
What happens when copper metal reacts with potassium cyanide?
Copper metal is less reactive than potassium so it will not react with potassium cyanide.
What happens when you mix copper sulphate with potassium Hexacyanoferrate?
A reddish-brown precipitate forms
What happens when potassium iodide is mixed with copper sulphate?
In the laboratory, copper(I) Iodide is prepared by simply mixing an aqueous solutions of potassium iodide and a soluble copper(II) salt such copper sulphate. : :: Cu2+ + 2I− → CuI2 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2. : :: 2 CuI2 → 2 CuI + I2
What happens when copper is added to copper sulphate?
Nothing
What happens when copper sulphate is dissolved in water?
Copper Sulphate mixed with hot water makes Copper Sulphate Crystals.
What happens if Copper Sulphate penta-hydrate is heated?
Copper sulphate pentahydrate loses water of crystallisation and becomes white amorphous anhydrous copper sulphate.
What happens when you mix copper sulphate and iron together?
iron sulphate will be created

What happens when you heat copper with sulfur?
The product is Copper Sulphate. Formula = CuSO4
