Piv txwv li ntsev yaj hauv dej feem ntau suav tias yog a lub cev hloov pauv, txawm li cas los xij cov hom tshuaj hauv ntsev (hydrated sodium thiab chlorine ions) txawv ntawm hom hauv ntsev.
Vim li cas cov ntsev yaj hauv dej hloov tshuaj?
Vim li cas Dissolving s alt is a Chemical Change
Yog li ntawd, dissolving ntsev hauv dej yog ib qho tshuaj hloov. Cov reactant (sodium chloride, los yog NaCl) txawv ntawm cov khoom (sodium cation thiab chlorine anion). Yog li, txhua yam ionic compound uas yog soluble hauv dejyuav ntsib kev hloov tshuaj.
Yuav ua li cas ntsev hauv dej yog dab tsi?
Thaum ntsev tov nrog dej, ntsev dissolves vim covalent bonds ntawm dej muaj zog dua cov ionic bonds hauv cov ntsev molecules. … Cov dej molecules rub cov sodium thiab chloride ions sib nrug, rhuav cov ionic bond uas tuav lawv ua ke.
Puas yaj ntsev hauv dej puas hloov pauv tau?
Kev ntsev ntsev hauv dej yog hloov pauv tau.
Puas yog kev piam thaj hauv dej puas hloov lub cev?
Dissolving qab zib hauv dej yog a lub cev hloov pauv vim tias cov piam thaj molecules tau tawg mus rau hauv dej tab sis cov piam thaj molecules ntawm tus kheej tsis hloov. … Hauv cov tshuaj hloov pauv cov molecular muaj pes tsawg leeg ntawm cov khoom hloov pauv tag nrho thiab tsim cov txheej txheem tshiab.
