Abstract: This paper looks at how we can make science labs safer and cleaner by using natural indicators instead of harsh chemicals. Usually, scientists use synthetic dyes to tell if a liquid is an acid or a base, but these can be bad for the environment. Our study shows that we can use colorful parts of plants—like red cabbage, flower petals, and fruit skins—to do the same job. These natural options are cheap, easy to find, and do not create toxic waste. We explain how these plant dyes change color just like the lab chemicals do, making them perfect for schools and green laboratories. By switching to these "earth-friendly" tools, we can follow the rules of green chemistry and protect our planet while still doing great science.
