When you're in the lab, finding signs of chemical reactions can be super exciting! Here are some easy ways to notice what's going on:
Color Change: One of the simplest things to see is when a liquid changes color. For example, if you mix an acid with a special dye and it goes from yellow to pink, that's a big sign that something is happening!
Gas Production: Sometimes, you’ll notice bubbles forming. This means that a gas is being made. If you mix baking soda with vinegar, you'll definitely see lots of frothy bubbles. It’s just like a mini volcano!
Temperature Changes: Touch the container! If it feels hot (that’s called an exothermic reaction) or cold (this is called an endothermic reaction), that’s another sign that a reaction is taking place.
All these observations make chemistry much more fun and exciting. Plus, they help us learn more about the reactions!
