Tuam Tshoj Chaw Tsim Khoom Sodium Thiosulphate Raw Salt, Sodium Thiosulphate, feem ntau luv luv li Hypo, yog ib qho tseem ceeb inorganic sulfur ntsev nrog ob lub ntsiab lus lag luam: sodium thiosulphate pentahydrate (CAS 10102-17-7) thiab anhydrous sodium thiosulphate (CAS 7772-98-7). Pentahydrate sodium thiosulphate tshwm sim ua cov xim tsis muaj pob tshab monoclinic siv lead ua nrog cov efflorescence ntuj hauv huab cua qhuav, thaum anhydrous sodium thiosulphate yog dawb zoo hygroscopic hmoov nrog cov khoom ruaj khov ntawm chav tsev kub. Ob qho khoom muaj cov dej solubility zoo heev thiab kev ua haujlwm tsis muaj zog, uas yog lawv cov yam ntxwv tshuaj lom neeg tseem ceeb.
Peb lub Hoobkas tswj hwm cov txheej txheem ntxuav kom huv si kom ntseeg tau tias cov ntsuas kev huv si ruaj khov. Pentahydrate sodium thiosulphate tswj hwm qhov tsawg kawg nkaus 99% cov ntsiab lus, thiab hom anhydrous ncav cuag 98.5% min purity. Peb tsim ob qib txheem: qib duab thiab qib kev lag luam dav dav, nrog cov hlau hnyav thiab cov khoom tsis huv uas ua raws li cov qauv xa tawm thoob ntiaj teb.
