2)Acetic Acid, HC2H3O2

What are the properties of Bases? - answer 1)Produce hydroxide ions (OH-) in water
2)pH greater than 7
3)Bases are proton (H+) acceptors
4)Bases neutralize acids to produce salts & water

What are the definitions of Arrhenius on Acid and base? - answer 1) He found that
aqueous solutions of acids and bases *conducted electric current*, therefore acids and
bases must *produce ions*.

3)Bases - produce OH- ions

What are the definitions of Bronsted-Lowry on acid and base? - answer 1)Acid: H+
donor (*Proton donor*)
2)Base: H+ Acceptor (*Proton acceptor*)
3)Acids and bases always come in pairs
HCl(g) + H2O(l) ↔ H3O+(aq) + Cl-(aq)
HCL is acid and H2O is a base.

What is "conjugate base" ? - answer It is the particles formed when an *acid give up
