Cov hlau nplaum tsis yog soluble nyob rau hauv dej vim: Lawv tau tuav ua ke los ntawm kev muaj zog metallic bonds thiab yog li tsis muaj cov kuab tshuaj rau cov tshuaj lom neeg tuaj yeem muaj zog dua li cov no, yog li cov tshuaj no yog insoluble lawv kuj tsis muaj qhov tsim nyog intermolecular rog (xws li hydrogen daim ntawv cog lus ) uas muaj nyob rau hauv dej.
Ua li no, puas yog cov hlau nplaum yaj hauv dej?
Tsis zoo li ionic compounds, lawv ua tsis yog yaj hauv dej , tsis ua lawv ua hluav taws xob.
Kuj Paub, puas covalent bonds yaj hauv dej? Covalent Compounds hauv Dej Thaum twg covalent compounds yaj hauv dej Lawv tawg mus rau hauv cov molecules, tab sis tsis yog tus kheej atoms. Dej yog polar solvent, tab sis covalent compounds feem ntau yog nonpolar. Qhov no txhais tau tias covalent compounds feem ntau tsis ua yaj hauv dej , es tsis txhob ua ib txheej nyias ntawm lub cov dej nto.
Ua raws li qhov no, puas cov hlau nplaum ua hluav taws xob thaum yaj hauv dej?
Thaum twg yaj hauv dej , lawv tsis ua hluav taws xob.
Dab tsi ntawm daim ntawv cog lus yog soluble hauv dej?
1 Teb. Covalent daim ntawv cog lus tsis txhob yaj hauv dej , tab sis ib co covalent compounds ua. Covalent molecules yog attracted rau ib leeg los ntawm ntau yam intermolecular rog xws li H- daim ntawv cog lus , dipole-dipole rog, thiab London dispersion rog. Dej molecules yog attracted rau ib leeg los ntawm muaj zog H- daim ntawv cog lus.

Yuav ua li cas yog tag nrho yaj yaj nyob rau hauv lub pas dej ua ke?
Koj cov khoom tawg tag nrho, lossis TDS, tus nqi yog qhov ntsuas ntawm tag nrho cov khoom uas yaj hauv koj lub pas dej. Cov pas dej da dej yuav tsum muaj qhov siab tshaj TDS tus nqi ntawm ib ncig ntawm 1,500 txog 2,000 ppm. Piv txwv li, cov dej haus tuaj yeem muaj qhov siab tshaj TDS tus nqi ntawm 500 ppm raws li EPA
Puas yog ntsev yaj hauv dej spontaneous?
Kev daws ntawm NaCl hauv dej muaj ntau qhov kev txiav txim tsawg dua li cov dej ntshiab thiab cov ntsev crystalline. Entropy nce txhua lub sij hawm ib tug solute dissolves nyob rau hauv ib tug hnyav. Txawm hais tias qhov hloov pauv enthalpy yog tus lej zoo, qhov kev sib cais yog tshwm sim vim hais tias Gibbs tsis muaj zog hloov pauv, G, yog qhov tsis zoo vim lub sij hawm entropy
Puas yog cov kua qaub tsim hydronium ions thaum lawv yaj hauv dej?
Cov kua qaub yog ib qho sib xyaw uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, cov kua qaub yog ib yam khoom uas tsim hydronium ions (H3O +) thaum yaj hauv dej. Thaum hydrochloric acid (HCl) yaj nyob rau hauv dej, nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions
Puas yog aragonite yaj hauv dej?
Cov kws tshawb fawb tshwj xeeb tshaj yog nyiam nyob rau hauv aragonite, uas yog tsim los ntawm ntau tropical corals, txias-dej coral, pteropods thiab ib co molluscs. Nws yog soluble ntau dua li calcite. Cov plhaub tsis muaj kev tiv thaiv thiab cov pob txha pob txha yaj thaum cov carbonate ions hauv dej tsis tshua muaj - nws tsis txaus los yog corrosive
