Indicators are really useful for spotting changes in chemical reactions! They help us see signs that a reaction is happening. Here are a few ways indicators show us what’s going on:
Color Change: Many indicators change color based on how acidic or basic a solution is. For example, litmus paper turns red in acids and blue in bases. When we see a color change in a reaction, it often means something chemical is taking place.
Gas Production: Some reactions create gas, and we can often see this as bubbles. An indicator like the limewater test can tell us if carbon dioxide is produced. If it is, the limewater will turn cloudy.
Temperature Changes: Changes in temperature can also be important indicators. Some reactions give off heat (we call these exothermic), while others take in heat (these are endothermic). By using a thermometer, we can measure these changes to confirm that a chemical reaction is happening.
From my experience, these signs make chemistry feel more exciting and lively. What might seem like a boring experiment can turn into something really interesting!
