Reaksi Cairan Jeruk Lemon (C6H8O7) dan NaoH terhadap Tegangan dan Arus yang Dihasilkan dengan Penambahan Katalis Karbon Aktif

Abstract

Lemon is an environmentally friendly electrolyte. However, an innovative concept is needed to improve the quality of lemon electrolytes. The purpose of this study is to investigate the effect of activated carbon catalyst addition on the voltage and current electric generated from liquid lemon (C₆H₈O₇) and NaOH. Lemon juice group containing acetone (C₃H₅O) and 3 carboxylic acid group (COOH). The experimental study was performed using voltaic cells. The data measured is 125 ml of an electrolyte solution of lemon juice (C₆H₈O₇) and NaOH 10 grams. To the solution was added 5 grams, 7.5 grams and 10 grams of activated carbon catalyst. The results showed that the addition of activated carbon can accelerate the breaking molecular bond NaOH and C₃H₅O (COOH)₃ which decomposes into ions react with NaCH₂COO ⁺ and Cu ²⁺ cathode into a reductant then OH^- from NaOH reacts with the anode Zn²⁺+2e be the oxidant While H₂O react exothermically. Produces a voltage between 800-1130 mV second. It occurs when electrons flow from the anode interested Zn²⁺ + 2e react with H₂O and of  Zn²⁺ + 2e electrons pass led and resistor toward the cathode Cu²⁺. Cathode Cu ²⁺ reacts with C₆H₈O₇ and NaOH. The currents that produced ranged from 33.846 to 43.462 mA second. The mechanism of this voltage and current generation makes LED light was on.
