Yi-hygroscopic. Iyancipha ngokulula xa idibana nee-oxides kwaye inefuthe elibi. Isisombululo esinamanzi si-acidic kwaye asinyibiliki etywaleni. Yi-hygroscopic. Iyancipha ngokulula xa idibana nee-oxides kwaye inefuthe elibi. Xa ingaphezulu kwe-100℃, ukuphelelwa ngamanzi emzimbeni kuya kuvelisa i-anhydrous. Inyibilika emanzini, ayinyibiliki etywaleni, kwaye ikwinkqubo yekristale ye-monoclinic. Ilahleko yamanzi kwi-100°C.
