OBJECTIVES
This study was conducted to create pH indicators from flower extracts from the plants Clitoria ternatea, Bougainvillea glabra, and Adenium obesum.
It is aimed to:
a) find flower extract that is the most fitted for making pH indicator;
b) analyze the effect of the flower extract to different substances with varied pH
(1-14); and
c) create a color pattern analysis for each reaction of the extract with the substances with pH 1-14
find out if the age of the extract affects its ability to react with substances of various
