What happens when chlorine gas is bubbled through aqueous sodium bromide? And the chemical equation
Chlorine gas replaces the bromide ion to release Br2 liquid.
Cl2(g) + 2NaBr(aq) ==> Br2(aq) + 2NaCl(aq)
When chlorine gas is bubbled through aqueous sodium bromide, a reaction takes place between them. The reaction can be represented by the following chemical equation:
Cl2(g) + 2NaBr(aq) -> 2NaCl(aq) + Br2(aq)
In this reaction, chlorine gas (Cl2) reacts with sodium bromide (NaBr) to produce sodium chloride (NaCl) and bromine (Br2). The sodium chloride formed remains in the solution as it is soluble in water, while the bromine is also soluble and forms a reddish-brown color in the solution.
When chlorine gas (Cl2) is bubbled through aqueous sodium bromide (NaBr), a chemical reaction occurs. Chlorine is more reactive than bromine, so it displaces bromine from the sodium bromide compound. The chlorine atoms combine with the sodium atoms to form sodium chloride (NaCl), and the displaced bromine atoms combine to form elemental bromine (Br2).
The chemical equation for this reaction is:
Cl2 + 2NaBr -> 2NaCl + Br2
In this equation, the chlorine gas reacts with two molecules of sodium bromide to form two molecules of sodium chloride and one molecule of elemental bromine.
To arrive at this equation, you would need to understand the reactivity series, oxidation-reduction reactions, and the chemical properties of chlorine and bromine. By understanding these concepts and the periodic table, it becomes clear that chlorine will displace bromine from sodium bromide to form sodium chloride and elemental bromine.
