Question

Which product would form if chlorine gas was bubbled through a solution of sodium bromide

Answer 1

The products are sodium chloride (
`NaCl`) and bromine (
`Br_2`)

Step-by-step explanation:

Hi, when the chlorine gas is bubbled it produces a redox reaction because of its high reactivity with the sodium compared to the bromine.

So you will have to hemireactions:

`2Br^- \longrightarrow Br_2`

`Cl_2 \longrightarrow 2Cl^-`

Combining both equations and adding the sodium:

`2Br^- + Cl_2 + 2Na^+ \longrightarrow 2Cl^- +2Na^+ Br_2`

`2NaBr + Cl_2 \longrightarrow 2NaCl + Br_2`

Answer 2

This is what is normally termed a single replacement reaction, although don't hold me to that. It could have changed to something more modern.


`Cl_(2) + NaBr \longrightarrow Br_(2) + NaCl`
