Ib kua qaub yog ib qho compound uas yaj hauv dej los ua ib hom kev daws teeb meem. Chemically, ib kua qaub yog tej yam khoom uas tsim hydronium ions (H3O+) thaum yaj hauv dej . Thaum hydrochloric kua qaub (HCl) dissolves nyob rau hauv dej , nws ionizes, splitting mus rau hauv hydrogen (H +) thiab chlorine (Cl-) ions.

Tom qab ntawd, hom tshuaj twg ionizes tag nrho thiab tsim hydronium ions thaum yaj hauv dej?

Piav: Ib kua qaub yog ib yam khoom uas cuam tshuam nrog dej los tsim ntau tshaj hydroxonium ions hauv cov kua dej. Hydroxonium ions yog tsim los ntawm cov tshuaj sib txuas ntawm cov pa oxygen ntawm cov dej molecules thiab cov protons tso tawm los ntawm kua qaub vim nws ionization.

Ib yam li ntawd, dab tsi ua rau hydronium ions hauv dej? Raws li Arrhenius 'lub tswv yim ntawm acids, ib tug acid yog xws li ib tug compound uas thaum yaj nyob rau hauv dej , tso proton(s) los yog H+. Tam sim no raws li Arrhenius acid tso tawm H +, cov proton ua ke nrog H2O molecule los tsim H3O + ion qe ib hydronium ion.

Yog li ntawd, dab tsi ion yog tsim thaum lub acid yaj nyob rau hauv dej?

hydrogen

Yuav ua li cas thaum acid yaj nyob rau hauv dej?

Thaum ib acid yog yaj nyob rau hauv dej Nws tsim hydrogen ions (H +) uas ua ke nrog dej los 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 hlawv.
