Review
How can covalent compounds (acids) conduct?
-React with water
-Ionizes
Ionization vs Dissociation
-HCl ionizes in water (combine)
-NaCl dissociates in water (separate)
Acids
-HCl, HC2H3O2 , HNO3, citric acid.....
-Definitions:
produce H+ in water (Arrhenius)
proton donor (Bronsted-Lowery)
Electron-pair acceptor (Lewis) **** Important for Organic
-We often leave the water out but “know” it is there
