What does it mean to dilute something?

When you dilute something, you reduce the concentration of a solute. Imagine buying a nice, cold drink and taking a swig. It's too sweet for you! All you want to do is guzzle down the rest, but you know that all that sugar will give you a headache. You certainly don't want to throw the drink away, so you try to think of a way to make it less sweet. Suddenly, you realize the solution-- just put some water into it! By adding water, the drink will be less sweet and you won't waste any of it.

Creative Applications

  1. Does adding water change the volume of the drink?
  2. Does the amount of sugar in the drink change?
  3. What would happen if you combined your new drink (the one mixed with water) with another original one? Would the sugar be more or less concentrated than if you combined two original ones?
