<br/><br/>   ABSTRACT :  The acidic or basic nature of materials is usually determined using pH meter and commerciallt-sold or synthetic indicating means. In this study, an eco-friendly pH indicator was prepared from the aqueous and ethanolic extract of kamias  (averrhoa bilimbi L.) flowers containing anthocyanin pigment. TheKamias pH indicator paper was calibrated using buffer solutions pH O to 14 to come up with a colored chart. This served as reference in the subsequent effectiveness and acceptability tests conducted of the product. The indicator produced showe a highly acceptable response from the respondents provingthat it can be a good alternative to commercially - sold pH indicating means. The shelf-life test also revealed taht it could withstand the storage time of 3 months without losing its effectivity. These finding have significsnt implications to further refine the product and prolong its storage time,and consequently, the production of Kamias pH indicator paper.
