What is the difference between iodine and iodide?
iodine is a neutral molecule I2. and iodide is a negative charged ion I-. Iodine=Heavy rare element. Iodide=Compounds with iodine in formal oxidation state. I am pretty sure Iodine the the elemental name, but in reference to a compound Eg potassium iodide, you change the ending.
In iodometric titration how is iodine liberated either by oxidation or reduction?
Ioding when combined in a compound is usually combined as the iodide. Iodide ions are negatively charged (ie each ion has an extra electron compared with an iodine atom). When elemental iodine is liberated, iodine atoms are formed from these ions which in turn pair up to form iodine molecules. When an Iodine ion changes into an atom it must lose the extra electron. From the acronym 'OILRIG' (Oxidation Is Loss of electrons, Reduction Is Gain of electrons) it is clear that as the elemental iodine has formed because of the loss of an electron the process must involve oxidation.
Why hydrogen iodide is a reducing agent?
Because it contains Iodine in its lower oxidation state of -1
What is AlI3 in chemistry?
Aluminum (III) Iodide the aluminum uses it's +3 oxidation state therefore it is named Aluminum (III) and since it is ionic the Iodine just uses Iodide
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.
What is the difference betweet iodine and iodide?
In Iodine, the element is in 0 oxidation state, but in Iodide it is in -1. Iodine = I2 , Iodide = I- Iodine can exist freely, but Iodide cannot.

What is the oxidation state of iodine in tetrabutylammonium iodide?
The oxidation state of iodine in the compound in the question is -1, as it is in any compound with a name that properly includes the word "iodide" instead of "iodine". "Iodide" is the name of the anion with formula I-1.
Does the iodine solution change color?
Yes, it may appear yellow due to oxidation of iodide ions

What element do you get when you break down potassium iodide?
By mild oxidation you'll get Iodine, I2
Why hydrogen iodide is a reducing agent?
Because it contains Iodine in its lower oxidation state of -1
What is the name of an iodine ion?
An iodide ion is an iodine atom with a −1 charge. Compounds with iodine in formal oxidation state −1 are called iodides. This can include ionic compounds such as caesium iodide or covalent compounds such as carbon tetraiodide.
What are the differences between the compounds and elements that make potasssium iodide?
Potassium Iodide is made up of two elements : Potassium and Iodine. Potassium is a alkali metal while Iodine is non metallic and halogen. Potassium is strongly basic, while Iodine is strongly acidic. In this compound potassium is in +1 oxidation state, while iodine is in -1. Aqueous solution of Potassium Iodide can dissolve Iodine to make Potassium Tri-iodide, KI3, which is brownish in colour.
What is the ionic compound name for MgI2?
MgI2 is also known as Magnesium Iodide. This is a molecule of magnesium that is bonded to two molecules of iodine.
What is AlI3 in chemistry?
Aluminum (III) Iodide the aluminum uses it's +3 oxidation state therefore it is named Aluminum (III) and since it is ionic the Iodine just uses Iodide
How do you make a pure sample of Iodine?
mix common arsenic with soap. mix common arsenic with soap.
