40 IB Chemistry IA Ideas

Welcome to our blog post on IB Chemistry Internal Assessment (IA) ideas!


If you're an IB Chemistry student, you know that the IA is a crucial part of your coursework and can make or break your final grade.


However, coming up with a research question can be a daunting task, so we've compiled a list of 40 potential IA ideas for you to choose from.


Whether you're interested in studying the effect of temperature on ferromagnetics, variations in enthalpy, or the connection between metal ion charge density and thermal stability, we've got you covered.


It's important to note that these ideas should be used as a starting point and not as a definitive answer, but with Prodigy Prompt's help, you'll be sure to ace your IA report!


But that's not all... Once you've chosen your research question, Prodigy Prompt can help you generate example sections of your report that are tailored to your chosen topic.


This way, you can be sure that your IA report is well-structured, evidence-based, and meets all the requirements of the IB Chemistry syllabus.

So, without further ado,👇 let's dive into our list of 40 IA ideas👇


We hope that you'll find something that piques your interest.
