Regarding my previous question, the past paper question "Suggest two steps you would use to obtain pure dry liquid bromine" - I think that the question is asking on how to purify the sample and not how to obtain the bromine from a bromide.

Freshly prepared bromine condensed to a liquid can be purified by drying with concentrated sulphuric acid, and then re-distilling the dry bromine over potassium bromide to remove any chlorine present.
