Coulometry
Coulometry is a way to measure how much electricity is used in a chemical reaction.
Let's pretend you're making lemonade. You have a big bowl of lemons and you need to know how much sugar to add so you don't make it too sweet or too sour.
To measure the amount of sugar you need, you could add a little bit at a time and taste it after each addition. This is like how chemists used to measure things in the past, before coulometry was invented.
But now there's a better way. You can use a special tool that measures the electrical charge that's used up as you add sugar to the lemonade. This tool is called an "electrode".
The electrode is like a little wire that's put into the lemonade. When electricity flows through the wire, the sugar in the lemonade reacts with it and uses up some of the electrical charge.
By measuring how much electrical charge was used up, the electrode can tell you exactly how much sugar you added to the lemonade.
This is how coulometry works. Instead of using taste to measure the amount of a substance in a reaction, coulometry uses electrical charge to get a precise measurement.
