Sodium Thiocyanate Ph
Kev qhia tshwj xeeb
Sodium Thiocyanate (Nextan) yog dawb, deliquescent, crystalline khoom nrog molarlass loj ntawm 81.07 g mol⁻¹. Heev soluble hauv dej, ethanol thiab acetone, nws decooses saum toj no ~ 300 degree, tso cov roj sulfur thiab nitrogen oxides. Qhov sib xyaw ua ke yog qhov tseem ceeb tshaj plaws ntawm cov thiocyanate anion thiab tau tshaj nrog ntau cov kuab tshuaj polar, ua rau nws muaj ntau yam reagent rau ob qho txheej txheem kev lag luam.
