INDIKATOR ALAMI_LUH PUTU SRI TISNAWATI

Hi guys, my name is Tina. I'm from class 12F1, with number ASEN 25. On this occasion, we will try a pretty simple particle, which is a natural indicator particle. What is a natural indicator? This natural indicator is a substance that comes from plants or other natural materials. This natural indicator is used to identify a sour taste and a wet taste. Okay, forget about the wet taste, let's take a closer look at this particle. Hi guys, there are ingredients used in this natural indicator experiment, which are quite simple. The first is water as a detergent. This detergent contains NaOH or hydroxide. The second is vinegar as an acid, which contains CH3COOH or acetate acid. There is also a test, which is an eggplant flower with the name Ilmiah Yutoria Ternate, and turmeric with the name Ilmiah Curcuma Longa, where we have removed the turmeric and eggplant flowers, so that there is no residue left, only the color remains. Okay, how many times is the result? Let's try it. Okay, in the first experiment, we put this eggplant flower in the wet. Next, we put this eggplant flower in the acid. This is the result. Next, we will put this turmeric in the wet. Next, we will put this turmeric in the acid. And the result is like this. Well, this is the result of our experiment in the natural indicator. And when this eggplant flower contains anthocyanin, which is a sign of pH change, we put it in the wet, it will turn blue. And when we put it in the acid, it will turn red to light red. And turmeric, we put it in the wet, it will turn brownish orange. And when we put it in the acid, it will turn neutral or yellow. Well, that's it, it's a pretty simple practice that you can try in your daily life. See you in the next practice, bye!
