What happens when you mix CuSO4 and Ki?
So, when potassium iodide,KI is added to the copper sulphate, CuSO4 solution, then they will undergo redox reaction in which iodide ion reduces cupric ion, Cu2+ to cuprous ion, Cu2+ (blue to white precipitate)and it themselves get oxidized to iodine gas.
What product is formed when Ki reacts with CuSO4?
> Copper sulphate reacts with potassium iodide to form potassium sulphate, cuprous iodide and iodine.
Does KI and CuSO4 form a precipitate?
Cu(II) reacts with iodide to form CuI2, which immediately reacts to CuI and elemental iodine, thus resulting in a colourless precipitate and a brown solution (if excess iodide to form I3– is present).
What happens when Cu2+ is treated with KI?
When Cu2+ ion is treated with KI, a white precipitate is formed.
Is CuI a precipitate?
Properties. CuI is poorly soluble in water (0.00042 g/L at 25 °C), but it dissolves in the presence of NaI or KI to give the linear anion [CuI2]−. This dissolution–precipitation process is employed to purify CuI, affording colorless samples.
What happens when Cu reacts with KI solution?
When Cu^2 + ion is treated with KI , a white precipitate is formed.
What happens when CU 2 is treated with KI?
[SOLVED] When Cu^2 + ion is treated with KI , a white precipitate is formed.
What Colour is CuI?
white
Pure copper(I) iodide is white, but samples are often tan or even, when found in nature as rare mineral marshite, reddish brown, but such color is due to the presence of impurities….Copper(I) iodide.

Which is the correct equation for CuSO4 and Ki?
CuSO 4 + KI → CuI + I 2 + K 2 SO 4 Word equation: Copper (II) sulfate + Potassium iodide → Copper (I) iodide + Iodine gas + Potassium sulfate Type of Chemical Reaction: For this reaction we have a double replacement (sort of) reaction. Balancing Strategies: This is a little bit of a challenging reactions.
What happens when copper sulfate is mixed with potassium iodide?
Copper sulfate react with potassium iodide to produce copper(I) iodide, iodine and potassium sulfate.
How can I change the coefficient in front of the Cui?
You can do this by changing the coefficient in front of the CuI. You should end up with four iodine atoms on the product side of the equation. The coefficient in front of CuI should be two. Next update the KI. And the coefficient shouldn’t be two. If playback doesn’t begin shortly, try restarting your device.
