[PDF][PDF] Investigation of a simple and cheap source of a natural indicator for acid-base titration: effects of system conditions on natural indicators
This study investigated a natural indicator for acid-base titration which is extracted from
guinea corn leaves popularly called “waakye leaves” in Ghana. Four types of acid-base
titration were studied: strong acid versus (v/s) strong base, strong acid versus weak base,
weak acid versus strong base, and weak acid versus weak base. The indicator color
change, pH range and the average titre values were determined for each type of acid-base
titration. These values were comparable to those obtained from three standard indicators …
