HCl yaj hauv dej (H2O). Cov hydrogenions (protons) react nrog dej tsim hydronium ions (H3O) thiab chloride ions yog dawb hauv kev daws. H-Cl covalent bond ispolar. Nyob rau hauv ib tug polar daim ntawv cog lus cov electron khub sib koom ntawm ob atomsis attracted ntau dua electronegative atom.

Xav txog qhov no, puas yog HCl soluble lossis insoluble?

dej

Yuav ua li cas thaum HCl yaj hauv dej? Hydrochloric acid yog cov khoom ntawm hydrogenchloride yaj nyob rau hauv dej . Hydrogen chloride yog heev polar ces nws dissociates tsim hydrogen ions thiab chlorine ions nyob rau hauv dej . Cov hydrogen ion tso tawm pab txhawb rau acidic yam ntxwv ntawm hydrochloric acid.

Ib yam li ib tug yuav nug, puas yog hydrochloric acid dej soluble?

Ib feem vim nws qhov polarity siab, HCl yog heev soluble hauv dej (thiab lwm yam polar solvents). Thaum sib cuag, H2O thiab HCl ua ke los ua hydroniumcations H3O+ thiab chloride anionsCl los ntawm ib tug reversible tshuaj tiv thaiv: HCl + H2O → H3O+ + Cl.

Vim li cas acid yaj hauv dej?

Thaum ib kua qaub yog yaj hauv dej Nws tsim hydrogen ions (H +) uas ua ke nrog dej tsim cov hydronium ion (H3O +). Thaum twg Cov kua qaub Yog Dissolved Hauv Dej Nws Cov txheej txheem Exothermic heev thiab tuaj yeem ua rau Burns.
