Acids and Bases

Question 1

Properties of Acids

Answer 1

1) Taste Sour
2) Corrosive
3) React with bases to neutralize

Question 2

Properties of Bases

Answer 2

1) Taste bitter
2) Corrosive
3) React with acids to neutralize

Question 3

What is an Arrhenius Acid and Base?

Answer 3

Acids: a source of H+
Bases: a source of OH-

Question 4

Limitations of Arrhenius Acids and Bases

Answer 4

1) It was limited to only aqueous solutions
2) Cannot account for substances like NH3
- NH3 is a base

Question 5

What is a Bronsted-Lowry acid and base?

Answer 5

Acid: A proton (H+) donor
Base: A proton (H+) acceptor

Question 6

What is a Lewis acid and base?

Answer 6

Acid: electron-pair acceptor
Base: electron-pair donor

Question 7

What form are acids and bases commonly found?

Answer 7

Acids and bases are commonly found in aqueous solutions

Question 8

What does the K constant represent?

Answer 8

The K value is determines the strength of the acids and bases. The strength of the acids and bases are related to the equilibrium constant for the ionization reaction.

Question 9

What does a large K value mean?

Answer 9

A large K value indicates:

1) solution is a strong acid / weak base
2) greater dissociation
3) Higher concentration of H+ (can be written as [H+] )

Question 10

In definition of acids and bases do they have conjugate pairs?

Answer 10

The Bronsted-Lowry Acids and Bases have conjugate pairs

Question 11

Will have a strong base have a high K value?

Answer 11

No, a strong base will have a low K value

Question 12

True of False:

Will a strong acid have a weaker base

Answer 12

True

Question 13

What are the common strong acids?

Answer 13

1) HNO3 (Nitric Acid)
2) HSO4- (Hydrogen Sulphate)
3) CH3COOH (Acetic Acid)
4) HCN (Hydrocyanic Acid)
5) H2O (Water)
