Hi,
I made the titration of battery sulfuric acid that I bought with NaOH to find its concentration as it was not given (and found without surprise around
35,1% w/w). Having no burette I made the titration on large scale to compensate for the lack of precision so I now have quite a good quantity of
Na2SO4, just slightly contaminated by a few drops of very dilute bromothymol blue.
I was wondering what I could use it for. All I found is that It could be used as a drying agent. Are there other uses? Thank you.

None that I know of.

1. Make alum : sodium aluminum sulfate.
2. Add it to Ca(NO3)2 to get solid CaSO4 and NaNO3 in solution
3. If you do #2, you can also do : CaSO4 + 2 C → CaS + 2 CO2

The thermal properties seems really interesting I might try something with that one day. The 3 reactions does not give really interesting chemicals to
me but it's good to know anyway, thank you !
