11.3 Strengths of Acids and Bases

Question 1

What is a strong acid?

Answer 1

Bronsted Lowry acid that completely dissociates in water

Question 2

What is a weak acid?

Answer 2

Bronsted Lowry acid that partially dissociates in water

Question 3

What is the acid-ionization constant?

Answer 3

Ka = equilibrium constant for an acid dissociation reaction

Question 4

What does it mean if Ka > 1?

Answer 4

the products are favored and the acid is considered strong

Question 5

What does it mean if the Ka < 1?

Answer 5

reactants are favored and the acid is considered weak

Answer 6

hydroiodic
hydrobromic
hydrochloric
perchloric acid
sulfuric acid
nitric acid

Question 7

What does a larger Ka value indicate?

Answer 7

Question 8

What is the base-ionization constant?

Answer 8

equilibrium expression for the dissociation of bases in water

Question 9

What does a Kb > 1 mean?

Answer 9

products are favored and the base is considered strong

Question 10

What does a Kb < 1 mean?

Answer 10

reactants are favored and the base is considered weak

Question 11

What are common strong bases?

Answer 11

group one hydroxides, group one oxides, some group two hydroxides, and metal amides

Question 12

What does polyprotic mean?

Answer 12
