How can I make HCl or H2SO4?

[ercdndrs]

I'd like to make some hydrochloric acid or sulphuric acid for an experiment, but unfortonately many of the methods I've read so far either use materials which I don't have access to, or are questionable as to whether or not they will work.

 

I've put together a list of chemicals I DO have access to (not including regular household chemicals, like NaHCO3 and NaCl).

 

-Ammonium Chloride (NH4Cl)

-Sodium Bisulphate (NaHSO4)

-Calcium Hydroxide (Ca(OH)2)

-Hydrogen Peroxide (H2O2)

-Calcium Chloride (CaCl2)

-Sodium Dichloroisocyanurate (C3Cl2N3NaO3)

-Ammonium Iron (III) Sulphate 12 Hydrate (NH4Fe(SO4)2)

 

I also have a graphite rod that could be used as a fairly unreactive electrode.

 

Finally, before people come at me with "You can buy those acids at the hardware store" etc, I've checked and no, I can't. Maybe it's because I live in Canada, or that my town has a population of 4000...

 

Anyways, any (helpful) answer would be greatly appreciated.

Edit:

 

I've had some ideas and some of them I've seen on this site; I've written the reaction equations:

 

NaCl + NaHSO4 + Heat -> HCl + Na2SO4

 

2 CaCl2 + 2 NaHSO4 -> 2 CaSO4 + 2 NaCl + H2 + Cl2

 

I've tried the second method by mixing the two salts in room temperature water, there were very small bubbles (hydrogen?) but no chlorine smell, and a white powder that wouldn't dissolve (CaSO4?). Although there was no Cl2 produced is it possible that the chlorine was simply dissolved in the water?

 

Thanks
