Ionization Of Acids And Bases
Chapter Name : Equilibrium |
Sub Topic Code : 102_11_07_12_08 |
Topic Name : Ionization Of Acids And Bases |
|
Sub Topic Name : Factors Affecting Acid Strength |
|
Introduction
• Since the degree of dissociation tells about
the strength of an acid we can see that the extent of dissociation of an acid
depends on the strength and polarity of the H-A bond.
•
In general, when strength of H-A bond decreases, that
is, the energy required to break the bond decreases, HA becomes a stronger
acid.
Pre-Requisites:
Reaction, ionization,
water, acid, base
Activity:
Some foods are acidic in nature some are basic
Real Life Question:
Why is sulfuric acid
a strong acid…?
