Welcome to the podcast site for Allery Tutors. This is home to a range of weekly podcasts designed to offer revision material for AS and A Level Chemistry. These will be ideal if you are studying or thinking about studying A Level Chemistry and can be downloaded to create your own library of revision soundbites. Should people ask questions regarding A Level Chemistry I will answer them just contact me via my twitter page @allerytutors my facebook page 'allery tutors' and via my site I also have a YouTube channel with revision videos on too, feel free to take a look and subscribe.

Scripts for each podcast are available here so you can read and listen! A much more effective way to learn. Print them off and scribble notes all over them. Click here to get them.

My aim is to make A Level Chemistry as accessible as possible and I hope through the medium of podcasting I can achieve this! Love Chemistry!!

Please support these podcasts by making a donation. I run these podcasts to help other students understand chemistry however there are costs associated with it that I cover out of my own pocket. Donations will keep this project viable and will allow a more rapid expansion of the podcasts and development of more products to aid your revision! I would love to run a live progamme with the right technology! Thank You!!

Redox reactions a little bit like the shower gel! You certainly will be coming out of the exam with the sweet smell of success after listening to this podcast. Get stuck in to redox equations and how to construct half equations correctly and combine to form ionic equations with a neat method. Find out the difference between oxidising and reducing agents and oxidation and reduction. Not only that, but work out the agents from any equation! You don’t need to be a secret agent to crack this one!

Stand for the national anthem of the Oxidation States of Chemistry! Sounds very grand doesn’t it? It certainly is an important part of chemistry and plays a role in most areas of Chemistry. Listen to this podcast to find out about what oxidation numbers are, the rules of oxidation states and the exceptions (there is always one!). Find out how you can work out oxidation states of elements within a molecule and what the romans contributed to this!

Initiate your revision, propagate your knowledge and Terminate with your exam! Yes it can only mean free radical mechanisms! This podcast looks at the process to make haloalkanes from alkanes via free radical substitution and a bit of Ultra Violet. This reactive bunch of chemicals have been linked to damaging of ozone via CFCs but also have very important uses as you will find out. All the equations, all the explanations and the tips to avoid the exam pitfalls. You will have heard of fishing well in chemistry there is fission, Homolytic and Heterolytic to be precise. Totally radical!!!

Caution this podcast is on fire! Well not quite, but it does contain content of a flammable nature! Listen in to find out about how alkanes are used as fuels and the difference between complete and incomplete combustion with equations! There is also a look at the nasty side by looking at how the pollutants are formed – Nitrogen Oxides, Sulphur Dioxide, Carbon Dioxide and Monoxide and particulates! Ouch! There are some more equations thrown in too. Finally we look at how to reduce these by looking at catalytic converters and flue gas scrubbers! Now your cooking on gas!

What a cracking topic! Well it has to be alkanes and petrochemicals. This podcast will look at alkanes and how they are extracted from crude oil using fractional distillation. It also explores the uses of the fractions e.g. diesel, petrol, LPG, Kerosene and bitumen. There is even a talk of saturated and unsaturated molecules. Finally it looks at catalytic cracking and thermal cracking to optimise the use of the crude oil.

Well Heston Blumenthal stuff this is. When you listen to this podcast you will find out what a Barium Meal is and why it is used. There is a bit more standard chemistry in here too by looking at solubility of group 2 hydroxides and sulphates. To top it all off this podcast is bulging with uses of toxic Barium Sulphate, Calcium Hydroxide, Magnesium Hydroxide, Calcium hydroxide and Oxide as well as using a metal to extract another and scrubbing! All funny things going on here!

What do you do with dead atoms? You Barium! Yes... that was a group 2 chemistry joke! Listen to this podcast to find out about the reactivity of the alkali earth metals (Beryllium, Magnesium, Calcium, Strontium and Barium) their reactions with water, oxygen and acids. You will also find out the reactions of group 2 oxides and hydroxide and also settle that burning question you have all been asking! What is the difference between a base and an alkali? Well all will be revealed in this Earth themed podcast!

You may have heard of a price comparison site, well this is a bond comparison podcast! A neat little sound bite that summarises all the bond types, structures and physical properties. Find out the similarities and differences between covalent bonds, ionic bonds and metallic bonds. Not only that but find out how the structure affects physical properties and when you should talk about intermolecular forces when explaining melting and boiling points. All this and some example questions for you to have a crack at! Brilliant!

Sep 19, 2015

Do you have a steely determination to succeed in Chemistry? Well this podcast on metallic bonding will help you to succeed! Listen in to find out about what a metallic bond is and find out about the physical properties of melting and boiling points, malleability, ductility, strength and electrical and thermal conductivity. There is also a link with toast and jam! Seems odd but take a listen to find out more.

Sep 12, 2015

Watch out James Bond there is a new bond on the scene - POLAR BOND! Well at least in this podcast! Take a listen to find out what this polar bond is what electronegativity is. Explore the attractive world of intermolecular forces such as van der waals, dipole dipole and hydrogen bonding. Find out why these are so important when trying to explain physical properties of compounds. Stick with it, it will be worth it!

This podcast contains one of the most precious minerals on Earth! Yes, get your ear full of covalent molecules such as diamond, graphite, crystal and.... sewer gas! The variety of covalent molecules! You will find out about the difference between simple molecular and giant covalent, how their structures affect physical properties like melting point and electrical conductivity and a bit of dative covalent bonding too! As usual it is packed with try it yourself questions to make sure you undersatnd the stuff! Now that's handy!

Just like a country has an economy, Chemistry has one too, called the atom economy. Let your brain absorb the wonders of this as well as percentage yield and empirical formula. Just to give you a little insight, you will find out how to calculate them all with little tips to help you grab all the marks in the exam. Not only that, but there are links to industry, highlighting the importance of yield and atom economy. Certainly not economical with the chemistry here!

Trying to titrate tests a titrator's time! Say that quick 3 times! Thankfully titrations doesn't have to be as difficult as that! In this podcast you will find out what a titration is as well as the reasons why we do specific things when doing a titration such as why we swirl the flask during a titration. All these are common 'How Science Works' concepts and vital for your practical exams! Not only that I will give you a neat way to calculate concentrations from a titration and how to make a standard solution! Ever wondered what language meniscus comes from?
