Chaw Tsim Khoom Zoo Tus Nqi Ammonium Bifluoride CAS: 1341-49-7

piav qhia luv luv:

Ammonium hydrogen fluoride tseem hu ua acid ammonium fluoride. Cov mis tshuaj NH4F HF. Qhov hnyav molecular 57.04. Dawb deliquous hexagonal siv lead ua, lom. Nws yooj yim rau delix. Qhov ceev ntawm qhov sib piv yog 1.50, qhov melting point yog 125.6 ℃, thiab qhov refraction yog 1.390. Yuav sublimate, corrosive rau iav, kub lossis dej kub yuav decompose. Yaj hauv dej, me ntsis soluble hauv cawv. Aqueous kua yog acidic heev, tuaj yeem corrode iav, corrosive rau daim tawv nqaij. Gaseous ammonia tau ntxiv rau 40% ntawm hydrofluoric acid, tom qab ntawd txias thiab crystallized.

Txoj kev npaj: 1 mole ntawm ammonia dej kom nqus 2 moles ntawm hydrogen fluoride, thiab tom qab ntawd txias, concentration, crystallization.

Siv: Siv ua tshuaj reagent, earthenware thiab iav etching, electroplating, brewing kev lag luam, fermentation kev lag luam preservative thiab bacterial inhibitor, thiab lwm yam. Nws kuj yog siv rau hauv beryllium smelting thiab ceramic manufacturing.

Cov Khoom Siv Tshuaj： Dawb los yog tsis muaj xim pob tshab rhombic siv lead ua lub cev siv lead ua, cov khoom yog flake, saj me ntsis qaub. Me ntsis soluble hauv cawv, yooj yim soluble hauv dej txias, decompose hauv dej kub. Dej yog acidic heev thaum yaj.
