Introduction
We discuss the nature and names of the various oxoacids of halogens – the hypohalous, halous, halic and perhalic acids.
Pre-Requisites:
Halogens, Arrhenius acid-base theory, Electronegativity.
Activity:
The addition of water (hydrolysis) to interhalogen compounds leads to the formation of oxoacids.
Real Life Question:
How are salts in the manufacturing plants iodized?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Oxoacid | An acid containing oxygen in addition to another atom is called an Oxoacid. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| 3D structures or toys | To understand the structures of the compounds better with ball and stick models. |
Real life uses :
Iodic acid is used to iodize table salt for human consumption. Perchloric acid is used to make rocket fuel. Other acids are used for various other purposes in industry.
Places to visit :
Salt manufacturing plants: Salts of iodic acid are used to iodize the salts.
