Ob lub ntsiab yam cuam tshuam lattice enthalpy yog cov nqi ntawm cov ions thiab cov ionic radii (uas cuam tshuam qhov kev ncua deb ntawm cov ions). Sodium chloride thiab magnesium oxide muaj raws nraim tib yam kev npaj ntawm ions hauv cov siv lead ua daim kab xev , mas cov lattice enthalpies txawv heev.

Yog li ntawd, dab tsi yog qhov tsis zoo ntawm lattice enthalpy?

yog tias cov khoom muaj " ntau exothermic" lattice enthalpy . ces nws vim nws muaj ntau attraction bewteen nws ions tab sis uas nyob ib ncig ntawm nws thiab kuv tsis tau vim li cas LE yuav ua ntau exothermic vim li ntawd. Yog tias cov khoom A muaj tsawg dua tsis zoo enthalpy tshaj cov khoom B, ces cov khoom A yog cov tsis muaj zog ntawm ob lub lattices.

Kuj Paub, vim li cas lattice enthalpy txo qis pawg? a) Radius ntawm ions Raws li qhov loj ntawm halide nce nqes pawg , cov lattice zog txo . Qhov no yog vim tias nrog qhov loj ntawm ions, qhov kev ncua deb ntawm lawv cov nuclei nce. Yog li lub attraction ntawm lawv txo thiab thaum kawg qhov tsawg lattice zog tso tawm thaum lub sijhawm ua haujlwm.

Ib yam li ntawd, dab tsi yog txhais los ntawm lattice enthalpy?

Lattice enthalpy [edit] Lattice enthalpy tsuas yog qhov hloov pauv hauv Enthalpy txuam nrog kev tsim ntawm ib tug mole ntawm ib tug ionic compound los ntawm nws gaseous ions nyob rau hauv tus qauv tej yam kev mob.

Lattice enthalpy cuam tshuam li cas rau solubility?

Raws li lattice zog nce, solubility yuav txo. Lattice zog yog tus nqi ntawm zog yuav tsum tau cais cov crystals rau hauv gaseous ions. Zog yog yuav tsum tau sib cais cov khoom, yog li cov lattice zog yeej yuav zoo.
