| Daim ntawv thov | Siv rau dyeing thiab luam ntawv wool fabrics, polyamide thiab txhob lo lo ntxhuav |
| Kev ua haujlwm zoo | Cov khoom tso tawm yog nruab nrab. Thaum dyeing, lub teeb xim yog xim liab thaum ntsib tooj liab ions, daj thaum ntsib hlau ions, thiab yeej tsis hloov thaum ntsib chromium ions. |
| Solubility | Me ntsis soluble hauv dej, cov tshuaj aqueous zoo li xiav-liab. Soluble nyob rau hauv ethanol (liab xim av), insoluble nyob rau hauv lwm cov organic solvents. Nyob rau hauv cov ntaub ntawv ntawm concentrated sulfuric acid, nws yuav reddish liab doog, thiab ces ua txiv ntseej xim av tom qab dilution. Nyob rau hauv lub xub ntiag ntawm concentrated sulfuric acid, nws ua xim av thiab sai sai yuav daj-lub teeb xim av. Nws cov tshuaj aqueous thiab hydrochloric acid tau ntxiv los tsim cov xim av tsaus nti. Qhov sib ntxiv ntawm cov tshuaj sodium hydroxide ua rau cov dej sib sib zog nqus liab. |
