Ntawm cua sov orthoboric acid saum 370k Cov ntaub ntawv metabolic, HBO2, uas txuas ntxiv mus cua sov tawm los boric oxide B2O3.
Ib yam li ib tug yuav nug, yuav ua li cas thaum Orthoboric acid yog rhuab?
Thaum twg boric acid yog rhuab Nws hloov mus rau metabolic kua qaub uas nyob rau ntxiv cua sov muab boron trioxide. Teb: Ntawm muaj zog cua sov , ua first Boric acid (H3BO3) tawg mus rau hauv Metaboric kua qaub (HBO2) thiab dej (H2O). Nyob rau ntxiv cua sov , Metaboric kua qaub tawg mus rau hauv Boric oxide (B2O3) thiab dej.
Tsis tas li ntawd, yuav ua li cas thaum acid rhuab? Thaum twg cua sov , yog 100% kua qaub poob sulfur trioxide gas, SO 3, kom txog rau thaum cov kua dej tsis tu ncua, lossis azeotrope, muaj txog 98.5% H 2YOG 4 yog tsim ntawm 337 ° C.
Tsis tas li lo lus nug yog, thaum Orthoboric acid yog rhuab qhov seem tshuav yog?
Boric kua qaub thaum cua sov siab tshaj 170C nws dehydrates tsim metaboric kua qaub . Metaboric kua qaub thaum cua sov saum toj no 300C nws ntxiv dehydrates tsim pyroboric kua qaub.
Puas yog boric acid yog protic acid?
Tsis yog, boric acid tsis yog a protic acid . Boric acid yog ib tug tsis muaj zog monobasic kua qaub . Nws tsis yog ib protonic acid tab sis ua raws li Lewis kua qaub los ntawm kev txais electrons los ntawm hydroxyl ion thiab nyob rau hauv lem tso H+ ions.

Yuav ua li cas tshwm sim thaum boric acid yog rhuab nrog ethanol thiab lub Vapor yog burnt?
Orthoboric acid reacts nrog ethyl cawv nyob rau hauv lub xub ntiag ntawm tsim conc H2SO4 los ua triethylborate. Cov vapors ntawm triethyl borate thaum ignited burns nrog ib tug ntsuab edged nplaim. Qhov no tsim lub hauv paus rau kev tshawb nrhiav borates thiab boric acid hauv kev tshuaj xyuas zoo
