Working electrode

A working electrode is like a pencil that can write and erase on a piece of paper, except instead of writing and erasing, it measures and changes the chemicals in a solution.

Think of a glass of lemonade - there are lots of different things floating around in there like sugar, lemon juice, and water. A working electrode is a tiny, special pencil that can detect and even change the amounts of these things in the lemonade.

In the case of the electrode, it's made up of a special material that can conduct electricity and an important chemical called a catalyst. This catalyst helps speed up chemical reactions in the solution. When the electrode is added to the lemonade, it can measure how much sugar, lemon juice, and water there is.

And if it needs to change the amounts, it can add or take away certain chemicals to make the lemonade taste better or more sour. Scientists use this type of electrode all the time to help them understand chemical reactions and make new and exciting discoveries in the field of chemistry.
