gamsat chemistry videos

 

 

Chemistry is very important for GAMSAT. You will find that a lot of biology and organic chemistry questions actually expect that you have a strong understanding of the concepts of general chemistry. The majority of these are provided by Chemguy who has over 200 HD videos covering all aspects of general chemistry and organic chemistry. We encourage you to visit his website as he has more videos than are listed here.

Please note that while these videos cover a large portion of the GAMSAT assumed knowledge, they are not an exhaustive study guide. You should also consult a textbook to consolidate your learning.

Periodic Table

Here Chemguy lays the foundations for general chemistry

 

 

Periodic Table Trends

It is important that you understand the general trends of the periodic table and why they occur.

 

 

Atomic Theory

You need to understand the basics of atomic theory if you are going to succeed at GAMSAT.

 

 

Balancing Equations

You won't be directly asked to balance an equation in GAMSAT question but it may be required to solve the problem.

 

Stoichiometry

GAMSAT expects you to be able to interconvert between moles and grams so make sure you have this down solid.

 

Limiting Reagent

The concept of a limiting reagent ties in with stoichiometry.

 

 

Bonding

Here Chemguy covers the basics of chemical bonding

 

 

Molecular Shapes

Sometimes you will need to be able to predict the shape of a molecule given its structure.

 

 

Hybridised Bonding

This may seem confusing at first but give it some time to sink in. You really do need to know about bond hybridisation and about the characters of each type of hybridised bond such as their length and strength.

 

 

Kinetics

Chances are you will see kinetics questions in GAMSAT so make sure you understand it thoroughly.

 

 

Rate Laws

This is an old GAMSAT favourite so please be prepared to dominate it.

 

 

Equilibrium

Alcohols are one of the most important functional groups in organic chemistry. For GAMSAT you need to know their structure, be able to name them, and be able to compare and contrast their properties with that of other functional groups. There's more to alcohols than drinking them!

 

 

Le Chatelier's Principle

This is an absolutely vital concept that you MUST understand!

 

 

Ideal Gases

You should know that PV = nRT and you should also be aware of the principles of an ideal gas.

 

 

Solutions

It is common for a GAMSAT unit to involve solutions so it is best if you understand them.

 

 

Phase Changes and Specific Heat

This is a little less likely to appear in GAMSAT but it is still worth knowing just in case (there have been questions on this in the past).

 

 

Vapour Pressure

You need to understand vapour pressure and Raoult's Law.

 

 

Boiling Point Elevation

This may pop up in GAMSAT so make sure you understand boiling point elevation and freezing point depression.

 

 

Thermodynamics I

Another GAMSAT favourite. This stuff is actually really easy so make sure you know it.

 

Thermodynamics II

A little bit of extra thermodynamics information...

 

Introduction to Acids and Bases

Acid-base chemistry is a very important concept that creeps into biology and organic chemistry.

 

pKa values

Expect to encounter pKa values in GAMSAT so you'd better know how to use them. Also make sure that you understand logs.

 

Conjugate Acids and Bases

It will help if you understand the concept of conjugate acids and bases.

 

Buffers

GAMSAT loves graphs and few topics are better suited to graphs than buffers.

 

Acid-Base Titrations

It is a good idea to understand the acid-base titration graphs. You shouldn't need to rote learn these - you should be able to derive them from your understanding of acid-base chemistry.

 

Introduction to Redox

In this video Chemguy introduces us to the wonderful world a reduction and oxidisation chemistry. This often appears in GAMSAT so ensure that you understand it fully. To help you remember which is which remember OILRIG - Oxidation electron Is Lost, Reduction electron Is Gained.

 

Balancing Redox Equations

ION the past there have been GAMSAT questions that require you to balance a redox equation. Such questions usually have an explaining passage but it will be much quicker and easier if you already know it.

 

 

Redox Half Reactions

Being able to break up redox reactions according to their half reactions is a key skill that may serve you well in GAMSAT.

Using Reduction Potentials

If you get a redox question in GAMSAT it will likely include a table of standard reduction potentials. Here Chemguy uses a table to solve a redox equation.

 

 

Galvanic Cells

So by now you should be getting the hang of redox, which is no small feat as it is one of the more complicated areas of chemistry. To top things off we will let Sal Khan of Khan Academy give us a lecture on galvanic cells.
