Strong & weak acids and bases Flashcards
1
Q
Strong acid
A
Completely dissociates in aqueous solution
2
Q
Weak acid
A
Partially dissociates in aqueous solution
3
Q
Why is a strong acid a strong acid?
A
It has a weak H-A bond that easily break
4
Q
Why is a weak acid a weak acid?
A
It has a strong H-A bond that needs more energy to break
5
Q
Acid dissiociation constant equation
A
ka = [H+] [A-] / [HA]
Equilibrium constant but for acids
6
Q
3 ways to determine strong and weak acids at equal concentration
A
- Strong acid has lower pH
- Strong acid reacts faster with metals
- Strong acid better conductor of electricity
