I'm having difficulty figuring out the best way to produce some HBr and later on some Elemental Bromine. I want to have the both basically

So far I'm finding preparations like (KBr + H2SO4), or (NaBr + H2SO4) to be common, but there's too many side reactions and byproducts.

I thought of why not use some of my hydrochloric acid 37% (is all I have) and buy some Sodium Bromide. My thinking is NaBr(ionic), HCl(polar covalent) would most likely react to form HBr and NaCl.

Somewhere on google a person recommended Peroxide(H2O2) as a oxidizing agent but I only have the weak store-bought 3% H2O2 H2O solution and have no clue if it would work, or exactly why it would help the reaction.

NaBr + HCl -> NaCl + HBr

without further recommendation I imagine adding HCl dropwise to a beaker of NaBr to form HBr which would then be seperated from the NaCl somehow. please suggest lol

but HBr is stronger acid then HCl ??

Would that make a difference in not being able to work?

I found this, anyone have good suggestions to it?

Let me get this right,

NaBr (s) + H2SO4 (aq) → HBr (aq) + NaHSO4 (aq)

and if I used H2O2 as an oxidizing agent I can avoid HBr and yield elemental Br?

NaBr (s) + H2SO4 (aq) + H2O2 (aq) → Br (aq) + NaHSO4 (aq)?  Please someone shine some light

Someone had tried that and it produces very little Bromine.
Probably the easiest way is to use high conc H2SO4 and NaBr.
By electrolysis, a good way is to use ZnBr2 since its melting point is 300 C or in that range.
