Question 1

Strong acid

Answer 1

An acid that will dissociate completely in aqueous solutions

Question 2

Monoprotic acid

Answer 2

An acid that dissociates to form one proton per molecule

Question 3

Diprotic acid

Answer 3

An acid that can dissociate to form two protons per molecule

Question 4

True or false? Sulfuric acid is a strong acid for both its first and second dissociation

Answer 4

False. Sulfuric acid is a strong acid for the first dissociation only

Question 5

Weak acid

Answer 5

An acid that will dissociate only partially in aqueous solutions

Question 6

Strong base

Answer 6

A base that ionizes completely in aqueous solutions

Question 7

Weak base

Answer 7

A base that ionizes only partially in aqueous solutions

Question 8

The stronger an acid, the __ its conjugate base

Answer 8

weaker

Question 9

The stronger a base, the __ its conjugate acid

Answer 9

weaker

Question 10

How do you use electricity conduction to tell which acid or base is stronger?

Answer 10

Stronger acids and bases are strong electrolytes and will conduct electricity better

Question 11

How do you use pH to tell which acid or base is stronger?

Answer 11

Stronger acids will have lower pH, and stronger bases will have higher pH

Question 12

How do you use the reaction with metal or carbonates to tell which acid is stronger?

Answer 12

Stronger acids will react more rapidly

Question 13

Why can’t titration with an indicator be used to distinguish between strong and weak acids?

Answer 13

If they have the same concentration they will have the same end point regardless of strength

Question 14

When can pH be used to compare acid strength?

Answer 14

Only when the concentrations are equal
