Combined Science - Feeling lost with the current topics?

At the moment, we are covering Topic 20 - The Chemistry of Acid, Bases and Salts. This is a chemistry topic. You can have a look at all of the topics we are going to cover here.

This topic is a continuation from Atomic Structure, Ionic and Covalent bonding and Chemical Formulae and Equations.

I have found a few video clips on youtube to guide you through these topics, just in case you have forgotten:

Atomic Structure -

• Parts of an atom 
• The nucleus
• What are electrons?

• Atomic number and mass number (in the Periodic Table)
•  What are ions?
• Isotopes

Bonding

• What are ionic bonds
• Covalent bonds (Part I) and (Part II)

Chemical Formulae and Equation

•  Formulae of ionic compounds (Part I)and (Part II (polyatomic ions))
• Calculating Mass

The Chemistry of Acid, Bases and Salts

• Acid-Base Reactions in Solution
• pH and indicators 

These video clips are at most 5 minutes and some are about 15 minutes, so do take time to watch them in your free time.
Oh! and just for fun, EXPLOSIONS! and Sulfuric Acid reaction with sugar!
