Pourbaix diagram

Imagine you're at a party and you have a cup of juice. You want to keep your juice safe from anything that might ruin the taste, like dirt or bugs. You also don't want to spill it or let it go flat.

A Pourbaix diagram is like a special map that scientists use to help them protect metals from damage. Instead of juice, it looks at different chemical elements and helps us understand how they react with other things around them.

The map shows different areas for different elements (like iron or copper) where they will stay safe from things that could damage them. It also shows which places are dangerous, where the elements might be attacked by other chemicals and become damaged.

This helps scientists figure out how to create things like rust-proof metals, so they won't get damaged and last a long time. The Pourbaix diagram is like a treasure map that helps scientists find the path to creating strong and long-lasting materials.
