Why does chlorine gas turn starch iodide paper blue?
Chlorine gas oxidizes some of the iodide ions in the paper to create iodine diatomic molecules. These molecules react with the iodide ions and the starch to form a charge-transfer complex, which has a striking blue color. It is thought that linear I3- and I5- ions occupy the center of the helix structure in the starch. These ions are formed by the reaction of molecular iodine with iodide ions.
Iodide reacting with chlorine to form iodine?
Iodide ions reacts with Chlorine to form elementary Iodine and Chloride ions
What happen in the reaction between chlorine and iodine ions?
The chlorine is reduced to chloride ions and the iodide {note correct spelling} are reduced to elemental iodine.
Why you add ki in to cuso4.5h2o in copper iodide test?
KI reacts with Cu2+ ions and then the CuI2 formed dicomposes to give insoluble CuI salt and I2. The iodine makes the solution brown. Cu2+ + 2I− → CuI2 2 CuI2 → 2 CuI + I2 Sodium thiosulfate can be added to this mixture. It reacts with the iodine giving a white ppt in a colourless solution.
What is the ionic equation for sodium thiosulfate?
S2O32-(aq) + 2H+(aq) ---> S(s) + SO2(g) + H2O(l)
Why KI is to be added to prepare to prepare iodine solution?
KI is potassium iodide, you'd react it with something to produce iodine ions. It reacts as reducing agent
What is the symbol for the ions that form when potassium and iodine react to form the ionic compound potassium iodide?
The cation is K+ and the anion is I-.
What two things react with lithium?
Lithium is a highly reactive metal, so it can react with many other ions, especially halogens such as fluorine, chlorine, bromine, and iodine

What product is formed after mixing BaCl2 and CuSO4?
Ba2+(aq) + SO42-(aq) --> BaSO4(s) The other ions, Cu2+ and Cl-, don't react (tribune ions).
What is the proper ratio for iodine and potassuim iodide?
The microbicidal effectiveness of pharmaceutical iodophor preparations comprising an organic substance which reacts with iodine to form a complex thereof, such as polyvinylpyrrolidone, iodine bound thereto in complex form, free iodine, and iodide ions, is assured by controlling the ratio of total iodine (complex bound iodine and free iodine) to iodide ions at between 2:1 and 10:1, this ratio being adjusted without chemical oxidizing agents such as iodate ions by anodic oxidation of a solution of the iodophor preparation and iodide ions. The resulting preparation can be free of chemical oxidizing ions such as iodate ions
What is the ionic bond Magnesium and Iodine?
Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.

How many ions in calciom iodide?
3 ions, 1 of Calcium and 2 of Iodine
Why does the concentration of iodine ions remains constant in the iodine clock reaction?
Iodine ion is not consumed; in the first step the iodine ion is oxidized to iodine, in the second step iodine is reduced to iodine ion.
