Question

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

Answer 1

Answer:

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

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.

$Cl_{2} + NaBr \longrightarrow Br_{2} + NaCl$
