Ammonium thiocyanate
Tshuaj Khoom ntawm ammonium thiocyanate qauv:
Ammonium thiocyanate qauv reacts nrog cov roj hlau los ua cov ntshav liab ferrocyanide, uas tsis hnov zoo nrog cov ntsev ferrous. Kev daws teeb meem liab nyob rau hauv tshav ntuj. THiotea tau tsim thaum ua kom sov li ntawm 140 degree. Ntawm 170 degree, nws decomposes rau hauv ammonia, carbon disulfide, thiab hydrogen sulfide. Yooj yim Deliquescent
