Titration

Okay, so you know how sometimes Mommy puts just the right amount of sugar in your lemonade so it's not too sour or too sweet? That's kind of like what titration is.

Titration is when we measure out a little bit of a chemical, usually with a dropper, and add it to another chemical, little by little, until we get just the right amount. We do this to find out how much of the second chemical we have.

It's like mixing different colors of paint to make a new color. We add a little bit of one color at a time, until we get the exact shade we want.

Scientists use titration to find out how much of a certain chemical is in something else. For example, if they want to know how much acid is in a cup of orange juice, they can use titration to measure it.

They start by adding a tiny bit of a chemical called an indicator to the orange juice. This helps them see when they've added enough of another chemical that reacts with the acid in the juice.

They keep adding the second chemical, drop by drop, until the color changes. When the color changes, they know they've added just enough chemical to react with all of the acid in the juice.

So, titration is like measuring out ingredients to make the perfect recipe, but it's for science!
