1. Lub cev lub cev
Kev tshwm sim: Txiv kab ntxwv-daj rau liab-xim av crystalline hmoov lossis flaky tawv ntawm chav tsev kub.
Ceev: Txog 3.357 g / cm3.
Melting taw tes: Txog 690∘c (decomposition, tsis tag tag nrho).
Kub taw tes: Txog 1750∘c (decomposition, tso cov pa oxygen).
Crystal Qauv: Orthaorhombic Crystal System, Lamellar qauv, yooj yim txhawm rau txhawm rau hauv cov plaub ya ri.
2. Tshuaj lom neeg
Oxidation: Oxidizer muaj zog, tshwj xeeb tshaj yog thaum muaj qhov kub thiab txias, tuaj yeem ua rau muaj cov tshuaj txo (piv txwv li cov pa roj av) thiab txo qis rau cov roj av tsawg vanadium oxides (piv txwv li, v2o3).
Acidity thiab Alkalinity: amphoteric oxide, tab sis predominantly acidic.
Cov tshuaj tiv thaiv nrog cov kua qaub: Dissolves nyob rau hauv muaj zog acids (piv txwv li sulfuric acid) los tsim vanadyloxy ions (vo 2+):
V2o {{5+ h2so4 → 2 {{{5} {{6} h2o
Cov tshuaj tiv thaiv nrog cov hauv paus: Dissolves nyob rau hauv lub hauv paus muaj zog (piv txwv li sodium hydroxide) los ua vanadates (piv txwv li navo3):
V2o {{5+2 na a naoh → 2navo 3+ h2o
Cov tshuaj tiv thaiv nrog dej: soluble me ntsis hauv dej los ua ib qho tsis muaj zog kua (ph ≈ 4), tsim HVO3 (Metavanadate).
