Law of dilution

Imagine you have a big jar of lemonade and you want to share it with your friends. But you find out that the lemonade is too strong and sour for them to drink. So you add more water to the jar to dilute the lemonade and make it less strong.

This is sort of like the law of dilution in science. A solution is a mixture of two or more substances that are evenly distributed. When you add more of a solvent (like water) to a solution, it makes it less concentrated and weaker. This process is called dilution.

The law of dilution says that the concentration of a solution is inversely proportional to the volume of solvent added. What this means is that the more solvent you add, the less concentrated the solution becomes. And the less solvent you add, the more concentrated the solution becomes.

For example, if you have a solution of salt water that is 10% salt, and you add more water to it, the concentration of salt will decrease. If you add enough water, the solution may become so dilute that you can't taste the salt anymore.

So, just like how you diluted your lemonade to make it more enjoyable for your friends, scientists dilute solutions to make them easier to work with or to reduce the concentration of harmful substances.
