[tex]2 Br^- (aq)[/tex] -----> [tex]Br_2 (g)[/tex] + [tex]2e^{-}[/tex]
The product formed at the anode is [tex]Br_{2}[/tex] (g).
Bromine can be produced by the electrolysis of molten sodium bromide.
In molten state ⇒ ions can move freely
Anions move towards the anode (oxidation site)
Cations move towards the cathode (reduction site)
So electrolysis extract electron from [tex]Br^-[/tex] and force electron onto [tex]Na^+[/tex]
In chemistry, the type of process in which decomposition of a chemical substance occurs due to the flow of electricity through the substance is generally known as the electrolysis process. Usually, the electrolysis process becomes in an arrangement in which one electrode of the cathode and one electrode of the anode are present.
In chemistry and production, electrolysis is a technique that makes use of direct electric present-day (DC) to power an otherwise non-spontaneous chemical response.
Electrolysis is commercially crucial as a degree inside the separation of factors from clearly going on sources including ores the usage of an electrolytic cell.
