Elektrolitička disocijacija

Vodeni rastvori kiselina, baza i soli provode električnu struju.

Zašto?

Iz fizike smo učili da je elktrična struje usmereno kretanje elektrona. Supstance koje provode el. Struju zovu se provodnici

I to su uglavnom metali.

Koje su to čestice koje u ovim rastvorima provode električnu struju?

Šta se dešava u vodenim rastvorima hidroksida, kiselina i soli?

NaOH→Na+ + OH-

Prema teoriji elektrolitičke disocijacije hidroksidi su jedinjenja koja disosuju u vodenom rastvoru na pozitivne jone metala i negativne jone hidroksidne grupe.

HCl →H+ + Cl-

Kiseline u vodenom rastvoru disosuju na pozitivne jone vodonika i negativne jone kiselinskog ostatka.

NaCl→ Na+ + Cl-

Soli u vodenom rastvoru disosuju na pozitivne jone metala i negativne jone kiselinskog ostatka.
