Sub Topic Code : 102_11_07_12_02 |
Topic Name : Ionization Of Acids And Bases |
|
Sub Topic Name : The Ionization Constant Of Water And Its Ionic Product |
|
Introduction
•
Some substances like water are unique in their ability
of acting both as an acid and a base.
•
In presense of an acid, HA it accepts a proton and
acts as the base
•
In the presence of a base , it acts as an acid
•
In pure water, one H2O molecule donates
proton and acts as an acid and another water molecules accepts a proton and
acts as a base at the same time.
Pre-Requisites:
Reaction, ionization,
water
Activity:
Lye, sodium hydroxide, is used to make soap as it dissolves grease
Real Life Question:
Why is lye used to
make soap
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Strong acid | good proton donor |
| Strong base | good proton acceptor. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Cleaning agents | Cleaning agents contain mild acids like phosphoric acid as they are corrosive in nature. |
