IB Chemistry: Topics 10 & 20

Organic chemistry is one of the bigger topics in terms of time and content. It takes up 11 of the 95 hours of Core time and 23 of the 155 hours allotted to the Core and AHL for Higher Level students. You will need to plan carefully how and when you intend to teach it. There are several different approaches that teachers have used successfully in the past. Some just plough through it as it is set out in the programme....

Hello Geoffrey,
Need your advice for an IA topic. Is this research topic good
'Determination of the concentration of ethanoic acid in vinegar'
Vinegar contains a small percentage of ethanoic acid, CH3COOH. This experiment intends to find out the concentration of the vinegar against a standard solution of sodium hydroxide solution of concentration 0.0934 mol dm-3 through acid-base titration.

Hi Khalida, Determining the percentage of ethanoic acid in vinegar using a standard solution of sodium hydroxide is fine to fulfill the mandatory experimental requirements for Topic 1.3. (Use of the experimental method of titration to calculate the concentration of a solution by reference to a standard solution) in the practical scheme of work but in my view it is far too simple for the IA, i.e. the individual scientific investigation.

Thanks Geoffrey for your inputs. Really helpful as this is the first IB year for me.
