Sub Topic Code : 102_11_07_12_05 |
Topic Name : Ionization Of Acids And Bases |
|
Sub Topic Name : Ionization Of Weak Base |

Introduction
•
The equilibrium constant for base ionization is called
base ionization constant and is represented by Kb.
•
It can be expressed in terms of concentration in
molarity of various species in equilibrium by the following equation:
•
Kb = [M+][OH–] /
[MOH]
Pre-Requisites:
Reaction, ionization,
water, acid, base
Activity:
Some foods are acidic in nature some are basic
Real Life Question:
Why is ammonia a weak
base as compared to Sodium hydroxide..?
