| Thesis Abstract |
<a href="DELA CRUZ, ELIZABETH ANN P., MONTES, PAULYN R., PASCO, ELLEN TRACY F., and POBLETE, FLORELYN T., Alugbati (Basella rubra Linn.), Dragon Fruit (Hylocereus undatus), and Ube (Dioscorea alata) as Acid-Base Indicators: An Experimental Study. Undergraduate Thesis. Science Education Laboratory School. Cavite State University- Rosario. April 2013. Adviser: Mrs. Marilou P. Luseco<br/><br/>A study was conducted to produce and evaluate liquid and paper acid- base indicators from alugbati fruits, ube, and dragon fruit peelings with four treatments: To- litmus paper and methyl orange, T₁- Alugbati (Basella rubra Linn.) indicator, T2- Ube (Dioscorea alata) indicator and T- Dragon Fruit (Hylocereus undatus) indicator. To make the liquid indicators, alugbati fruits were crushed then mixed with water and the ube and dragon fruit peelings were boiled. Part of each extract was used to make paper indicators. The reactions of each liquid indicator and each paper indicator on different chemical substances were tested considering the color reaction, rate of reactivity, and duration of reactivity.<br/><br/>For both liquid and paper, the ube indicator shows the most distinctive color reaction on different chemical substances within a month.<br/><br/>Data gathered proved that there is a significant difference between the rate of reactivity of the liquid and paper indicators on acids and bases within a month. There is no significant difference between the rate of reactivity of both liquid and paper indicators on neutral substances.<br/><br/>The ube liquid and paper indicators were reactive on acids and bases for thirty days. The alugbati liquid indicator was reactive for nine days. The alugbati paper indicator was reactive on bases for thirty days while on acids for twelve days. The dragon fruit liquid indicator was reactive for eleven days. The dragon fruit paper indicator was reactive on bases for thirty days while on acids for twelve days.<br/><br/>After the conduct of experiment and evaluation, the null hypothesis was rejected because there was a significant difference between alugbati, dragon fruit, and Ube acid-base indicators in terms of color reaction, rate of reactivity, and duration of reactivity on acids and bases. Based on the results, T2 is the best indicator since both liquid and paper indicators were reactive on acids and bases for thirty days. The researchers also concluded that the extracts of alugbati fruits and dragon fruit peelings can be base indicators while the extract of ube peelings can be an acid-base indicator.<br/><br/>From the findings and conclusion of the study, the following recommendations are hereby given:<br/>1. The use of alugbati, dragon fruit, and ube as pH indicators.<br/>2. Utilize other parts of alugbati, dragon fruit, and ube plants into acid- base indicators.<br/>3. Further study should be conducted for the comparison of alugbati, ube, and dragon fruit liquid indicators with paper indicators and with commercial indicators in terms of rate of reactivity, color reaction, and duration of reactivity.">DELA CRUZ, ELIZABETH ANN P., MONTES, PAULYN R., PASCO, ELLEN TRACY F., and POBLETE, FLORELYN T., Alugbati (Basella rubra Linn.), Dragon Fruit (Hylocereus undatus), and Ube (Dioscorea alata) as Acid-Base Indicators: An Experimental Study.
