This bundle contains four powerpoint lessons to support the reactivity 1.3 unit of the IB chemistry course. Covering combustion, fuels and fuel cells. All powerpoints are in line with the IB syllabus and contains essential definitions, exam questions and TOK talking points. This bundle also contains instructions for a full method for a biofuel making experiment
Fischer Esterification practical

Fischer Esterification practical

(0)
Worksheet for the synthesis of octyl acetate. Turn the smell of mothballs and vinegar into grapefruit! This is an undergraduate lab but if you have access to quick fit distillation apparatus and fume cupboards, it is perfectly doable at 16+ Great for a club or with Alevel students as a practical demonstrtaion of their organis chemistry knowledge. A fume cupboard is essential unless you want to stink out the whole department! Note - I forgot that esters are fantastic at dissolving plastics before doing this with students for the first time… stored their product in plastic vials that were completely destroyed… do not make the same mistake!
Exotic thermite investigation

Exotic thermite investigation

(0)
Worksheet/activity to investigate exotic thermites. Encourages practical use of essential chemistry numeracy skills, from molar quantities to enthalpy calculations. DISCLAIMER - This should not be attempted with students without experience in handling these substances! The reactions are very energetic and if done above the recommended quantities many of thermite reactions can get hot enough to melt crucibles. At the recommended quantities, the reactions can safely be done by students. Though care should be had with any Manganese thermite as these are often very quick! Do not stand directly over the reaction! Copper thermite should only be attempted with less energetic powdered zinc as with aluminium this one can be overly energetic. Basically don’t ever try this if you haven’t experimented with the different thermites yourself first. Having said that, I have run this several times with no problems If a reaction does not work it can be a great opportunity to explain why and to demonstrate the mathematics that correctly predicts the outcome. You can also use powdered magnesium for a more powerful reducing agent - though only with professional supervision This is great if you time for Alevel students or in a chemistry club
