Sodium thiosulfate
Sodium thiosulfate pentahydrate, tsis muaj crystal, tsw, muaj ntxhiab tsw qab. Cov kev nqus tshwj xeeb yog 1.729, rhuab rau 100 degree c, thiab 5 lub crystal dej poob. Soluble hauv dej, insoluble hauv dej cawv, decomposed nyob rau hauv acidic daws, nrog kev txo qis. Nws yooj yim huab cua nyob rau hauv qhuav huab cua saum 33 degree thiab deliquescent nyob rau hauv huab cua huab cua.
Sodium thiosulfate pentahydrate (ci dej qab zib / hisibo) yog ib qho tsis muaj xim thiab pob tshab siv lead ua. Nws yog cov hydrate ntawm sodium thiosulfate, soluble hauv dej, thiab cov kua aqueous yog qhov tsis muaj zog alkaline. Nws huab cua nyob rau hauv cov huab cua qhuav saum 33 degree c thiab poob cov crystal dej. Nws yog ruaj khov nyob rau hauv kev daws teeb meem nruab nrab thiab alkaline daws thiab yuav decompose sai hauv acidic daws.
