Apr 18, 2026

Tso lus

  • Qhov ceev: 1.651 g / cm³
  • Melting Point: 73 degree
  • Boiling Point: 200 degree
  • Cov tsos mob: tsis muaj xim rau daj ntseg daj, dej khov -zoo li cov muaju
  • Solubility: Yooj yim soluble hauv dej thiab ethanol
  • Chemical Properties: Maj mam oxidizes hauv huab cua los tsim orthophosphoric acid; Thaum cua sov rau 180 degree, nws decomposes rau hauv orthophosphoric acid thiab phosphine (muaj tshuaj lom heev). Phosphorous acid yog dibasic acid; Nws cov acidity yog me ntsis zog dua li ntawm phosphoric acid. Nws muaj zog txo cov khoom, tuaj yeem txo cov nyiaj ions rau cov hlau hlau thiab txo cov sulfuric acid rau sulfur dioxide. Nws muaj zog hygroscopic thiab deliquescent, nrog rau corrosive. Nws tuaj yeem ua rau kub hnyiab thiab ua rau tawv nqaij.
