QUOTE=beebopper;651517]Where do you get this from. Conc (pure) HCl is a liquid.
It is this person who needs some chemistry education. Hydrogen Chloride is a GAS. It is NOT a liquid at ambient temperature! It is a covalent compound and, as such, is unable to dissociate into ions.
I just checked wiki for its boiling point It is -85 Celsius!
Only when it dissolves in water - ie in aqueous solution - it forms HYDROCHLORIC ACID.
Obviously there will be water vapour in the atmosphere above honey, but I doubt that much, if any hydrogen chloride can be produced for the simple reason that Calcium oxide is basic and any free water would convert the hydogen chloride to hydrochloric acid which would then react with the base. There is the added problem that if that reaction occurs, then the calcium chloride (the drying agent) is no longer there!
And, OMG, there is far more calcium chloride used in ballasted tyres around the world than the small amount being used as a desiccant in laboratory experiments.
The effective way to trap water vapour from experiments, in my days of checking for labile tritium, was to collect any water in the gas stream by freezing. -196 Celsius did the job quite adequately and was the standard method employed. Not quite like the basic school classroom experiments, eh?
I think it is you who needs to go back to school. In my day, you would likely be stood in the corner wearing the dunce’s hat.
