Question

Chlorine gas was bubbled in a solution of sodium bromide. Explain what was
observed.​

Answer 1

When chlorine gas is bubbled in a solution of sodium bromide, the sodium bromide reacts and gives bromine which is a brown liquid and sodium chloride which is ordinary table salt.

Answer 2

A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:

2NaBr + Cl2 = 2NaCl + Br2
