1

The Arrhenius definition of an acid is a compound which ______, a base, one which _____.

forms H+ in solution
forms OH- in solution

2

By the Bronsted-Lowry definition, acids ______ and bases ______.

are species which donate hydrogen ions, and a base accepts them

3

An ______ acid/base is necessary a _____ as well, but the inverse is not necessarily true.

Arrhenius, Bronsted-Lowry

4

Bronsted-Lowry acids and bases occur in ____

pairs, always

5

A Lewis Acid is an A______

Acceptor of electrons

6

Acid/base definitions, from most inclusive to least:

Lewis, Bronsted-Lowry, Arrhenious

7

An ______ species is one that reacts like ______ in a _____ environment, and vice-versa.

amphoteric
a base, acidic

8

Acids formed from anions with names that end in -ide have the prefix hydro- and the ending - __.

ic
flouride becomes hydrofluoric acid

9

If an oxyanions ending in -ite (____ ____), the acid will end with -___ acid.

less oxygen
-ous acid

10

If the anion ends in -ate (_____ _____), the acid will end with - ____ acid.

more oxygen
-ic acid

11

For water at ____K, the water dissociation constant, Kw, has been experimentally determined to be ____. Given that each mole of water which autoionizes produces one mole each of hydronium and hydroxide ions, the conc of each is _______ in pure water or a neutral solution. If, however, the solution is acidic/basic, so long as the temp is still ______, the product of these two ion concentrations will always equal ____.

298K (25C)
10^-14
10^-7
298K
10^-14

12

Being an equilibrium constant, Kw is dependent only on changes in ______.

temperature

13

With a temperature above 298, Kw will ________, for the autoionization of water has an __________ nature.

increase, endothermic

14

pH + pOH =

14 at 298K

15

T/F: pH 7 is only neutral at STP

F: pH 7 is only neutral at 298K. Isolated changes in conc, pressure, or volume will not affect Kw.

16

the p value (neg log) of a number is 1.8 x 10^-5 =

e - 0.number
5 - 0.18 = 4.82
