Zinc hydroxide facts for kids
Zinc hydroxide is a special type of chemical compound. Its chemical formula is Zn(OH)2. This means it's made of zinc and hydroxide parts, called ions. Think of it like a tiny building block that chemists study.
What is Zinc Hydroxide Like?
Zinc hydroxide is a white, solid substance. It looks a bit like white powder. It doesn't mix well with water. If you put it in water, it won't dissolve.
But it can react with other chemicals! For example, it reacts with acids. When it does, it forms new substances called zinc salts. It can also dissolve in strong bases. These are chemicals opposite to acids. It even dissolves in ammonia, which is a common cleaning chemical. When it dissolves, it makes a clear liquid. If you heat zinc hydroxide, it changes into something else. It turns into zinc oxide, which is another zinc compound.
How is Zinc Hydroxide Made?
Scientists and chemists can make zinc hydroxide in a lab. They do this by mixing other chemicals together. For example, they can react zinc chloride or zinc sulfate with sodium hydroxide.
It's important to use a weak solution of sodium hydroxide. If the solution is too strong, the zinc hydroxide might dissolve instead of forming.
What is Zinc Hydroxide Used For?
Zinc hydroxide has a few interesting uses. One important use is in medicine. It is used in large bandages, especially after surgery. In these bandages, zinc hydroxide helps to absorb blood. This helps the wound stay clean and heal better.
