making sulfuric acid
in Inorganic Chemistry
Posted
Hey people, i just joined this forum, this is quite a fascinating site!
Ok, back to sulfuric acid.
I heated acid from battery until it starts smell ( SO3 came out, right?), i tried it on some tissue and did not burn it (guess around 90%~), so i used some chunks of anhydrous magnesium sulfate in a liebig distiller which sits on top of a small flask with the acid and starts to heating it, hoped to extract the water so i dont lose the SO3. it didnt work out well, so i just did a test batch and added anhydrous magnesium sulfate directly to the acid. it did fuzzed a bit and i think its the water crystallisation of mgso4...
So now i ended up around 96%~ acid since it slightly burns tissue when cooled down. But how do i separate the MgSO4.7H2O??
Do i distill the mixture to like 330~C and bubble it through another batch of 90% acid?
or is there otherways.
Thanks:confused:
