What colour is copper iodide and potassium sulphate?
Potassium sulfate would be colorless; copper iodide is probably blue or green (I don't know which off the top of my head, but copper salts are generally either blue or green).
What type of reactoin occur between CuSO4 and KI in biuret reagent?
2Cu(SO4) + 4KI --> 2K2(SO4) + 2CuI + I2Copper Sulfate + 2 Potassium Iodide --> Potassium Sulfate + Copper Iodide + Iodine
How is cuprous iodide prepared?
React a solution of Copper(II) sulfate with Sodium Iodide. It will produce Copper(II) Iodide and Sodium sulfate. This Copper(II) iodide, due to instability, spontaneously decomposes, producing Iodine and Copper(I) Iodide.The Copper(I) iodide comes out as a yellowish brown precipitate. So the overall reaction seems to be:2 CuSO4 + 4 NaI ----> 2 CuI + 2 Na2SO4 + I2
What happens when Potassium Iodide is added in Copper Chloride?
2K(I) + CuCl2 => 2KCl + Cu(I)2 The (I) is iodide, because the capital I and lowercase l look the same. This is a double replacement reaction, where copper (II) iodide comes out of solution, because it's not soluble, assuming that both of those are in solution.
Lead nitrate is treated with potassium iodide solution?
A precipitate of Lead iodide and Potassium nitrate are formed

What is the use of potassium iodide in the preparation of iodine solution?
somehow. the potassium iodide act as a acidifying agent,
Which one is more dense a solution of potassium iodide or a mixture of toluene and naphthalene?
The solution of potassium iodide (if it is not extremely diluted) is more dense.
What is the Symbol equation for silver nitrate solution and potassium iodide?
Silver nitrate + Potassium iodide ----> Silver iodide + Potassium nitrate AgNO3 + KI ----> AgI + KNO3
Mercuric chloride and potassium iodide?
Reddish precipitate of Mercuric iodide and clear solution of Potassium chloride is produced
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
A solution of potassium iodide is treated with iron III nitrate solution?
no
