Question
educe, using equations where appropriate, if bromine reacts with sodium chloride solution and with sodium iodide solution.[2]a.i
Solution
Bromine (Br2) can react with both sodium chloride (NaCl) and sodium iodide (NaI) solutions.
- Reaction with Sodium Chloride (NaCl):
Bromine is less reactive than chlorine, so it cannot displace chlorine from sodium chloride. Therefore, no reaction occurs when bromine is added to a sodium chloride solution.
- Reaction with Sodium Iodide (NaI):
Bromine is more reactive than iodine, so it can displace iodine from sodium iodide. The reaction is as follows:
Br2 + 2NaI → 2NaBr + I2
In this reaction, bromine (Br2) reacts with sodium iodide (NaI) to produce sodium bromide (NaBr) and iodine (I2). This is a displacement reaction where bromine displaces iodine.
So, bromine reacts with sodium iodide solution but not with sodium chloride solution.
