base
substance that dissociates IN WATER
Ex: NaOH (s) —> Na+ (aq) + OH-(aq)
Acids
undergo ionization IN WATER
HCl —→ H+ (aq) + Cl- (aq) 1st step is dissociation
H+ (aq) + H2O(l). —→ H3O+ (aq) 2nd step is postive H+ reacts with H2O to form H3O+
What does the acid ionization step look like?
HCl (g) + H2O —> H3O+ (aq) +Cl-(aq)
what is dissociation?
molescules dissociates into 2 or more compounds
Ionization
products of dissociation are charged ions
postive charge ion
cation
negeative charge ion
anion
electrolyte
form charged ions in H2O and letting water conduct electricty
how is electrolyte classfied?
based on degree of ionization in dilute solutions
strong electroylytes
dissoacite completley in dilute solutions + conducts electricty
strong acids or bases or ionic compounds
weak electroylytes
dissaoctictes partially in dilute solutions + partially conducts electricty
non-electrolyte
dont ioniz in water + dont conduct electricty
usually alchols or sugars
