Introduction
We look at what oxides are, and after differentiating between simple and mixed oxides, we classify the types of simple oxides.
Pre-Requisites:
Acid, Base, Oxidation State.
Activity:
Air pollution is caused by carbon dioxide, which is an oxide of carbon, emitted by everyday vehicles. Ozone holes are partly caused by oxides of nitrogen.
Real Life Question:
What is chalk made of? What are the components of crackers composed of?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Acidic oxides | Oxides which produce acids on reaction with water. |
| Amphoteric oxides | Oxides which produce both acids and bases on reaction with water. |
| Basic oxides | Oxides which produce bases on reacting with water. |
| Neutral oxides | Oxides which produce neither acids nor bases on reacting with water. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Flash cards | To remember the formulae involved. |
| Video aids | To understand how the reactions take place. |
| Home experiments | To understand the kinds of oxides. |
Real life uses :
Acids and bases form a very important part of our lives, and the types of oxides formed determine whether acids or bases will be created. Carbon dioxide is a very famous instance of an oxide that affects us every day.
Places to visit :
Vehicles emit carbon dioxide and pollute the atmosphere. Nitrogen oxides and sulphur oxides cause acid rain.
Practical examples around us
| Examples | Explainations |
|---|---|
| Pollution | Air and water pollution is mainly caused by the oxides of carbon, nitrogen and sulphur. |
| Chalk | It is derived from a compound made from calcium oxide. |
What you learn in Theory:
The types of oxides and their reactions with water, including the formulae.
What you learn in Practice:
What kinds of oxides form acids and bases, and how they do so.
