Investigation of water hyacinth and red cabbage to be used as pH Indicators
U Thet Paing Soe
Most of the pH indicators are natural indicators consisting of flowers, fruits and vegetables, they
can be used directly without toxicity and they can be obtained readily everywhere in the world.
At present, the control of pH is important in biochemical processes, analytical procedures,
agriculture and industrial processes. Hence, the role of pH indicators will become significant.
Therefore, this work is an attempt to investigate the naturally occurring species, flowers, fruits
and vegetables, which can be used as nontoxic, less expensive and readily available pH
indicators. In this research work, water hyacinth and red cabbage were investigated to be used
as pH indicators. Flowers of water hyacinth and vegetable of red cabbage were selected as
samples and tested to be used as pH indicators by using buffer solutions with pH values of 2, 4,
6, 7, 8, 10 and 12. The two samples red cabbage and water hyacinth were observed to be
suitable for the best pH indicators.
