Abstract: The role of pH indicator was used in various ways including measuring the pH of farm soil, different household substances and bodies of water. This comparative experimental study was conducted to prove and present an alternative pH indicator that can measure accurate pH level of a substance with distinct color change and wavelength that can be observed with the color chart of alternative pH indicator as the output of this study. In addition, this study considered the role of anthocyanin content of camote tops leaves extract on the absorption of light and in spectrophotometeric analysis and compare its efficacy with Phenol red. Researchers applied two concentration in testing: 300mL of water: 5 grams of camote tops leaves: 180 mL of ethanol; and 400mL of water: 5 grams of camote tops leaves: 240 mL of ethanol in different volume of 3mL, 5mL, and 10mL of camote tops leaves extract. The results indicated that both concentrations compared to Phenol red in terms of pH level and wavelength the two pH indicators showed no significant difference but had a significant difference in terms of color change. The researchers concluded that anthocyanins from camote tops leaves extract can be an alternative pH indicator that shows a wide pH range from 2-11 levels (pink as acid, green as basic to yellow in highly basic). The researchers developed a pH color chart of camote tops leaves extract recommended for measuring pH level of household substances, farm soil, bodies of water, and are readily available science experiments that can benefit farmers, teachers, and students.
