Click to learn and understand all the processes involved. Pada anoda terjadi oksidasi ion Br-, karena kation Br- lebih mudah teroksidasi daripada air (H2O). Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Sodium chloride melts at a completely high temperature of 801°C. So, as the brine (NaCl (aq)) becomes depleted in chloride ions, and the hydroxide ion is increasing (a by-product of the electrolysis), the probability of OH-ion oxidation to give oxygen is more likely, so you begin to get an increase in the O 2 /Cl 2 ratio in the product gases at the positive anode electrode the longer the electrolysis Contoh Soal Elektrolisis.
