Question 5

Props. of Acids

Answer 5

H+ > OH-
Electrolyte
Sour
Litmus: Red
REACTS WITH MOST METALS TO PRODUCE H2 (HYDROGEN GAS)

Question 6

Props. of Bases

Answer 6

H+ < OH-
Electrolyte
Bitter
Slippery
Does NOT react with metals
Litmus: Blue

Question 7

Bronsted Lowry Acid

Answer 7

Hydrogen ion donor

Question 8

Bronsted Lowry Base

Answer 8

Hydrogen ion acceptor

Question 9

Conjugate Acid-Base Pair

Answer 9

Differ by only one hydrogen

Question 10

Amphoteric

Answer 10

Acts as both an acid or base

Ex: Water

Question 11

Monoprotic and Polyprotic Acids

Answer 11

Mono: acid with 1 proton to donate: HCl

Poly: acid with more than 1 proton to donate: H3PO4

Question 12

Strong Acids’ Properties

Answer 12

Completely transfer hydrogen ion to water

Fully dissociates

Question 13

Weak Acids’ Properties

Answer 13

Partially transfer hydrogen ion to water

Partially dissociates

Question 14

Equilibrium constant Ka

Answer 14

Provides measure of the degree of ionization of the acid

Larger Ka, stronger the acid

Don’t include solids/liquids

Question 15

Equilibrium Constant Kb

Answer 15

Provides a measure of the degree of ionization of the base

Larger the Kb the stronger the base

Question 16

Important Formulas

Answer 16

pH=-log(H+)

pOH=-log(OH-)

pH + pOH = 14

Kw = [OH-][H+]

Kw= 1.0x10^-14

Question 17

0.1M of Ca(OH)2

Find pH

Answer 17

ONLY FOR BASES MULTIPLY THE CONCENTRATION BY THE NUMBER OF MOLES OF OH

0.1 x 2= 0.2

pOH=-log(0.2)=0.699
pH=14-0.699=13.301
