I have read a post "tweekaneere" in the Hydrochloric Gas sujet and i have take a little bottle 20 oz

and I add salt after I add a little sulfuric acid and i m wait ! wait and wait

one hour or no result

How long must I wait ?

Thank you for you re help .

Heu... visible reaction or no visible ?

I m use sulfuric acid 33% is too poor for this reaction ? or i can too wait many hours !?!
