Tin(IV) iodide facts for kids
-iodide-sample.jpg)
Tin(IV) iodide, also called stannic iodide or tin tetraiodide, is a special kind of chemical compound. A chemical compound is made when two or more different chemical elements join together. Its chemical formula is SnI4. This formula tells us that it is made of one tin atom (Sn) and four iodine atoms (I).
In this compound, the tin atom has a special electrical charge, which scientists call an oxidation state of +4. This means it has lost four electrons. The iodine atoms are present as ions, which are atoms with an electrical charge.

What Is Tin(IV) Iodide Like?
Tin(IV) iodide is a solid material that looks red-orange. Imagine a bright, rusty color!
How Does Tin(IV) Iodide React?
This compound can react with other substances. For example:
- When it mixes with water, it creates two new chemicals: hydriodic acid and tin(IV) oxide. Hydriodic acid is a strong acid, and tin(IV) oxide is another compound of tin and oxygen.
- It can dissolve in certain organic liquids. These are liquids that come from living things or are similar to them, like alcohol or oil.
- It also reacts with hydriodic acid to form a larger, more complex ion called SnI62-. An ion is an atom or group of atoms that has an electric charge.
How Is Tin(IV) Iodide Made?
Scientists usually make tin(IV) iodide in a laboratory.
Making It from Tin and Iodine
The most common way to make it is by mixing iodine with tin. When these two elements come together under the right conditions, they combine to form tin(IV) iodide.
Making It from Tin(IV) Oxide
Another way to create tin(IV) iodide is by reacting tin(IV) oxide with hydriodic acid. This method also produces the red-orange solid.
