Ionization Of Acids And Bases
Chapter Name : Equilibrium |
Sub Topic Code : 102_11_07_12_06 |
Topic Name : Ionization Of Acids And Bases |
|
Sub Topic Name : Relation Between KA And KB |
|
Introduction
• Ka and Kb represent the
strength of an acid and a base, respectively.
• In case of a conjugate acid-base pair, they
are related in a simple manner so that if one is known, the other can be
calculated.
•
It can be seen from the net reaction that the
equilibrium constant is equal to the product of equilibrium constants Ka and Kb
for the reactions added.
in case of a conjugate
acid-base pair,
Ka x Kb
= Kw
Pre-Requisites:
Reaction, ionization,
water, acid, base
Activity:
Some foods are acidic in nature some are basic
Real Life Question:
Why is Sodium
hydroxide a stronger base than ammonia..?
