Vim nws cov dej tsis muaj zog thiab ib nrab covalent thiab ib nrab ionic cim LiCl yog soluble nyob rau hauv dej zoo li acetone. Hauv Lithium fluoride lub lattice enthalpy yog siab heev vim me me ntawm fluoride ions. Hauv qhov no, hydration enthalpy yog tsawg heev. Vim li no, LiF yog insoluble hauv dej.

Yog li ntawd, yog LiF soluble hauv dej?

Yog li cas LiF , nws yog qhov opposite. Lub lattice enthalpy yog siab heev vim me me ntawm fluoride ions (piv rau lwm Halide ions); hydration enthalpy yog tsawg heev. Vim li no, LiF yog insoluble hauv dej.

Tom qab ntawd, lo lus nug yog, vim li cas LiF yuav luag insoluble hauv dej thaum LiCl yog soluble tsis yog hauv dej xwb tab sis kuj hauv acetone? LiF yuav luag insoluble hauv dej vim rau siab lattice zog. Tab sis LiCl yog soluble hauv dej vim rau High hydration zog ntawm Li + ion. covalent cim nce thaum nce qhov loj ntawm anion, yog vim li cas LiCl yog soluble hauv acetone (covalent compound) mas LiF yog insoluble hauv acetone.

Yog li ntawd, vim li cas LiF thiab CsI tsis soluble hauv dej?

Yog li cas CsI , ob qho tib si ions yog loj loj. Yog li ntawd, ob qho tib si ions hauv CsI tsawg hydrated thiab muaj me hydration enthalpy. Ntawm qhov tod tes, LiF yog yuav luag insoluble hauv dej vim nws siab lattice enthalpy. Ob lub ions hauv LiF yog me me thiab hnyav hydrated.

Yog vim li cas fluorides insoluble?

Solubility yuav siv sij hawm qhov chaw nyob rau hauv ob kauj ruam: tawg ntawm lattice ntawm ib tug compound: Lub zog yuav tsum tau tawg lub lattice thiab hu ua Lattice Zog / Enthalpy. Vim li no, tshuaj fluoride Cov tshuaj sib xyaw feem ntau yog tsawg soluble tshaj lawv cov chloride sib txuas.
