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
Copper and iodine reaction?
copper iodide
What is the composition of iodine solution?
Otherwise a solvent is stated, a solution of iodine contains only iodine molecules.
What is the difference between strong iodine solution and weak iodine solution?
their color
Is antiseptic iodine a solution or solvent?
The liquid product is a solution. The iodine is one of the solutes within the solution.
What is the indicator for carbohydrates?
Simple(sugar): benedicts solution. Turns bright orange. Complex(starch): iodine turns dark purple/black
What chemical is used to test for sugars?
Depends on the Sugar: Reducing sugars a normally monosaccharides but there are some disaccharides too like maltose. If its a reducing sugar then you would add Benedicts Reagent (alkaline copper(II) sulphate). You then heat it. if a reducing sugar is present then a precipitate is formed that will be red/orange. A Non-reducing sugar like Sucrose can be tested by first adding benedicts and heating. if no change is present you then add hydrochloric acid to hydrolyse the glycosidic bond. you then add a hydrogen carbonate solution to neutralise the acid. Then repeating the Benedicts and Heating process.

What is the Reaction of iron sulphate with potassium iodide?
no reaction in aq solution, but if both powder used iodine will be generated with so2 releasing.......i am trying to work out the mechanism
Is iodine solution ionic?
A solution of iodine is covalent.
What is the difference between iodine crystals and iodine solution?
Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
What is the formula for the reaction between Potassium iodide and copper sulphate?
General: 2KI + CuSO4 ----> CuI2 + K2SO4 The CuI2 immediately decomposes to iodine and insoluble copper(I) iodide, releasing I2.:: 2 CuI2 → 2 CuI + I2
What is the solution of tincture of iodine?
iodine
Copper and iodine reaction?
copper iodide
What is the change in color in testing for the presence of protein in egg albumin using solution sodium hydroxide and copper sulfate?
Copper sulphate when mixed with a protein will turn purple if the amount of protein is sufficient enough in quantity to trigger the reaction. Planex1234 says; No offense but i think it is starch that turns dark blue - purple. Thetada says: the colour changes are arguably similar. Iodine solution goes blue/black in the presence of starch. The colour that sodium hydroxide / copper sulphate solution goes in the presence of protein is variously described as mauve / purple.
How would you remove essentially all the iodine while leaving the water in the bag?
How to remove iodine from a solution of water? I'm assuming your talking about a iodine salt (such as sodium iodide) as elemental iodine (I2) is not that soluble in water. To remove simply add in another salt (such as copper sulfate) that will react with the iodide producing an insoluble salt (copper iodide) which can then be removed.
What is the composition of iodine solution?
Otherwise a solvent is stated, a solution of iodine contains only iodine molecules.
