Amiruddin, Muhammad Agung (2020) Pengaruh Penambahan Karbon Aktif Terhadap Cairan Jeruk Lemon (C6H8O7) Dan Naoh Pada Nilai Tegangan. Magister thesis, Universitas Brawijaya.
Abstract
Jeruk lemon merupakan salah satu elektrolit yang ramah lingkungan. Jeruk lemon mengandung gugus aseton (C3H5O) dan 3 gugus asam karboksilat (COOH) yang tergolong dalam elekrolit lemah. Tujuan dari penelitian ini adalah untuk menyelidiki pengaruh penambahan katalis karbon aktif cairan jeruk lemon(C6H8O7) dan NaOH terhadappembangkitan tegangan dan arus dari sistem batre sel volta. Penelitian dilakukan secara eksperimen nyatainstalasi sel volta. Data yang diukur adalah nilai tegangan dan hambatan yang dibangkitkan dari larutan 100 ml dan 125 ml elektrolit jeruk lemon(C6H8O7). Pada setiap larutan ditambah NaOH 10 gram dengan variasi penambahan karbon aktif sebagai katalis sebanyak 5 gram, 7,5 gram dan 10 gram. Dari hasil penelitian diperoleh bahwa penambahan karbon aktif pada elektrolit dapat meningkatkan nilai tegangan antara 20 mV sampai 100 mV disebabkan adanya ion dipol pada karbon aktif memiliki sifat keelektromagnetan secara fluktuasi. Hal ini menunjukkan karbon aktif mampu mempercepat pemutusan ikatan molekul jeruk lemon(C6H8O7) yang terdiri dari C3H5O dan 3 gugus COOHyang akan terurai menjadi ion-ion CH2COO- dan H+. Kation(Na+ dan H+) akan bereaksi dengan katoda Cumenjadi reduktor sementara itu anion (OH- dan CH2COO-) akan bereaksi dengan anoda Zn2++2e menjadi oksidator. Selain itu selama proses berlangsung larutan elektolit menghasilkan H2O dimana fenomena ini disebut reaksi eksoterm. Arus terjadi ketika elektron tertarik dari anode Zn+2+ 2e yang bereaksi dengan H2O menuju ke anoda led dan katoda led terhubung dengan resistor yang diteruskan ke rangkaian sel volta.
English Abstract
Lemon is one of the environmentally friendly electrolytes. Lemon juice group containing acetone (C3H5O) and 3 carboxylic acid group (COOH), which belong to the weak electrolyte. The purpose of this study was to investigate the effect of adding activated carbon catalyst liquid lemon (C6H8O7) and NaOH against voltage and the current generation of the voltaic cell battery system. The study was conducted in a real experiment installation of voltaic cells. Data were measured voltage and resistance value generated from a solution of 100 ml and 125 ml lemon juice electrolytes (C6H8O7). In each solution plus 10 grams of NaOH with the addition of activated carbon variation as a catalyst 5 grams, 7.5 grams and, 10 grams. The result showed that the addition of activated carbon to the electrolyte can increase the value of the voltage value between 20 mV to 100 mV due to the presence of dipole ions on activated carbon which has fluctuating electromagnetic properties. caused by the ion-dipole on activated carbon properties are fluctuations electromagnetism. This shows the activated carbon molecular bonds can accelerate the termination of lemon (C6H8O7) consisting of C3H5O and 3 COOH group which decomposes into CH2COO- ions and H +. Cations (Na + and H +) will react with Cu cathode into a reductant while the anion (OH- and CH2COO-) will react with the anode Zn 2+ + 2e be the oxidant. Additionally, during this process, a solution of electrolytes produces H2O where this phenomenon is called an exothermic reaction. Occurs when electrons flow from the anode interested Zn + 2 + 2e which reacts with H2O to get to the anode and cathode led resistor connected passed to a series of voltaic cells.
