EXPERIMENTAL INVESTIGATIONS IN pH BEHAVIOR AND CELL POTENTIAL OF Bryophyllum pinnatum SOLUTION

Abstract

All over the world, electricity production depends on non-renewable sources i.e. oil, gas and coal, which are limited natural resources. Under developed country like Bangladesh are always in shortage of electricity which is a clear barrier for development. It is high time to search for alternating energy sources. This paper introduces a new renewable biomass source in Pathor Kuchi Leaf (PKL) or Bryophyllum pinnatum solution. PKL has already undergone several testing processes and in this paper the pH behavior and Cell Potential is under investigation. These parameters are quite necessary before fully integrating PKL in Energy Grid. The experiment was conducted on 6 different PKL cell with different concentration of PKL juice. Cell no. 1 & cell no. 6 showed an initial pH of 3.37 and 3.40, which is quite acidic. PKL cells were also tested with a 5% CuSO4.5H2O solution which after being mixed together showed pH of 3.37. As for Cell Potential, a more theoretical approach was followed. For each unit cell 1.85 V cell potential was found which add up to 11.1 V for 6 cells. These results indicate a threshold for highest electricity generation from 6 unit PKL Battery.
