What is Zinc Iodide Like?
Zinc iodide is a solid that has no color, so it looks clear or white. It can easily dissolve in water, just like sugar or salt.
When zinc iodide mixes with certain chemicals called bases, it creates a new substance called zinc hydroxide. Zinc iodide is also known as a "reducing agent". This means it can give away electrons in a chemical reaction. When it does this, it changes into iodine.
How is Zinc Iodide Made?
Making zinc iodide is quite simple! You can create it by mixing zinc metal directly with iodine. It's like combining two ingredients to get a new one.
What is Zinc Iodide Used For?
Zinc iodide has a few interesting uses:
