Ionic compounds yaj nyob rau hauv dej yog hais tias lub zog muab tawm thaum lub ions cuam tshuam nrog dej molecules them nyiaj rau lub zog xav tau los rhuav tshem ionic bonds nyob rau hauv cov khoom thiab lub zog yuav tsum tau cais cov dej molecules kom lub ions tuaj yeem muab tso rau hauv kev daws teeb meem.
Tsis tas li cov lus nug yog, vim li cas ionic compounds soluble hauv dej?
Feem ntau ionic compounds yog soluble hauv dej . Qhov no yog vim polar dej molecules muaj zog attraction rau them ions . Tus nqi ions ua daws raws li lawv dissociate rau dej.
Tsis tas li ntawd, dab tsi ua rau lub compound soluble hauv dej? Zoo yog attracted rau qhov tsis zoo, ua ib tug cohesive qauv. Thaum polar tshuaj sib xyaw los yog ions ntxiv rau dej , lawv tawg mus rau hauv cov khoom me me, lossis yaj , los ua ib feem ntawm kev daws teeb meem. Cov cov dej ib nrab nqi nyiam qhov sib txawv ntawm cov compound , ua lawv soluble nyob rau hauv dej.
Ib yam li ntawd, koj yuav nug, dab tsi txiav txim siab solubility ntawm ionic compounds?
Solubilities ntawm ionic compounds muaj kev cuam tshuam los ntawm kev sib cuam tshuam ntawm cov kuab tshuaj, cov nyhuv ion, thiab kub. Muaj zog solute-solvent attractions nce solubility ntawm ionic compounds . Ionic compounds tsawg dua soluble yog cov kuab tshuaj uas muaj ib hom ion. Piv txwv li, CaSO4 yog me ntsis soluble hauv dej.
Dab tsi ionic compound yog soluble nyob rau hauv dej?
Rooj ntsev , los yog sodium chloride ( NaCl ), feem ntau ionic compound, yog soluble hauv dej (360 g / L).

Ib qho piv txwv ntawm ionic compound yog dab tsi?
Ionic compounds yog cov sib txuas uas muaj ions. Ob lub ntsiab lus feem ntau yog ionic thaum ib lub caij yog hlau thiab lwm qhov yog tsis yog hlau. Piv txwv li: sodium chloride: NaCl, nrog Na + thiab Cl-ions. magnesium oxide: MgO, nrog Mg2 + thiab O2- ions
Lub npe ntawm ionic compound BaCO3 yog dab tsi?
Teb thiab piav qhia: Lub npe ntawm BaCO3 isbarium carbonate. Ba + 2 yog barium ion, uas tshwm sim los ntawm abarium atom poob ob lub electrons. Carbonate yog polyatomicion
Dab tsi yog 5 yam khoom ntawm ionic compound?
Nov yog cov npe luv luv ntawm cov khoom tseem ceeb: Lawv tsim muaju. Lawv muaj ntau dua enthalpies ntawm fusion thiab vaporization dua li cov tebchaw molecular. Lawv nyuaj. Lawv yog cov nkig. Lawv muaj cov ntsiab lus melting siab thiab tseem kub kub ntsiab lus. Lawv ua hluav taws xob tab sis tsuas yog thaum lawv yaj hauv dej
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Yuav ua li cas tshwm sim nyob rau hauv ib tug ionic compound?
Ionic bonding yog kev hloov pauv tag nrho ntawm valence electron (s) ntawm atoms. Nws yog ib hom tshuaj lom neeg daim ntawv cog lus uas ua rau ob qho tib si tiv thaiv ions. Nyob rau hauv ionic bonds, cov hlau poob electrons los ua ib tug zoo them cation, whereas lub nonmetal txais cov electrons los ua ib tug tsis zoo nqi anion
