This is very off subject but I thought there might be some chemists out
there that could help me out. I'm trying to utilize Glauber's salt (soduim
sulfate) as a storage meduim for heat. Glauber's salt will hold 8120
BTU/cu ft compared to water which will hold only 3120 BTU/cu ft. The
Glauber's salt as it changes phase from liquid to solid gives off additional
latent heat during the phase change.
So everything that I've read says that the salt turns liquid at 90
degrees F . My salt is not turning to liquid. I'm using
anhydrous soduim sulfate. Any ideas on what is going
on? Thanks
