Na2SO4
Level 277 Chem lab, we identify our unknown substance as Na2SO4, and reproduced our unknown with a simple double replacement; 2NaOH + H2SO4 >
Na2SO4 + 2HOH. As part of our lab, we have to give a presentations on our unknown substance (Na2SO4). This compound looks boring, I was wondering if
anyone knows any interesting facts/experiments with Na2SO4.

I've yet to meet a truly boring compound! Na2S04 is not toxic or very reactive, so play around with it and do some simple experiments. See how much
you can dissolve in H2O, then try and grow some crystals. Will it make double salts (alums) the way K2SO4 will? A favorite of mine: see what happens
if you burn it...heat some up and watch it melt. Find out if it will decompose into something else.
Just don't eat it as it is a laxative! :-)

Its anhydrous form is very useful in drying organic liquids
