"Indikator alami asam basa"

The purpose of this experiment is first to learn how to make a natural indicator The second is to determine the acidic and basic nature of a substance using a natural indicator Before moving on to the video I will briefly explain some material about acids and bases themselves There are three figures who have proposed acid-base theories According to Arrhenius an acid is a substance that when dissolved in water produces H+ ions While a base is a substance that when dissolved in water produces hydroxide ions According to Brønsted-Lowry an acid is a substance that donates a H+ ion or a proton donor A base is a substance that accepts a H+ ion or a proton acceptor According to Lewis an acid is an electron pair acceptor while a base is an electron pair donor Next the properties of acids and bases The acidity itself the first one tastes acidic the second one has a pH below 7 The third one reacts with limestone and baking soda to produce gas The taste of the base itself the first one tastes bitter the second one has a pH above 7 The third one reacts with acid to produce salt and water An indicator is a complex compound that can react with acidic or basic compounds While natural indicators are indicators derived from naturally extracted materials It is used to determine the acidity or pH level of a solution The pH indicator is a substance that can show different colors in acidic solutions How do you determine if a solution contains an acid or a base The method is to conduct a laboratory experiment to determine acids and bases using natural indicators The indicators I use are turmeric hibiscus flowers and paper flowers Tools and materials the first is a mortar the second is a pestle the third is a stirrer The fourth is a sterile filter or syringe the fifth is a knife I use regular water as a neutral and shower soap water as a base lime juice as an acid and the natural indicator or test I use is First there is turmeric second there is water lily third there is paper flower Natural indicator First natural indicators can be made by taking the extract from the plant that will be used as an acid-base indicator No next lemon juice which is acidic because after being tested with litmus paper Lemon juice turns pink hibiscus turns pink turmeric becomes yellow ree soap alkaline because after being titrated with an indicator paper flowers bath soap changes color to its lilac color love flower changes color to beige and turmeric turns cream or red 4 and for regular water it is neutral Because it does not produce a color effect on each indicator
