turquoiseblue Posted September 1, 2017 Report Share Posted September 1, 2017 Hi guys, i'm really confused what what ib expects for a chemistry ia topic and would like to know whether a topic doesn't have to be measuring an effect of something, or can be also just determination of concentration of substance. Thanks for replies! Reply Link to post Share on other sites More sharing options...
HappyIB:) Posted September 1, 2017 Report Share Posted September 1, 2017 Check out the official IB website for IA samples or ibessays.org/samples Reply Link to post Share on other sites More sharing options...
Martijn.S Posted September 2, 2017 Report Share Posted September 2, 2017 It's advised you write your research question under the form of "What is the effect of X on Y?" (X being the independent variable, Y the dependent one). You could, for example, say: "What is the effect of the concentration of [product] on [catalyser]?". From that, you could find an ideal concentration, where the catalyser works at maximum efficiency. Through this process, you would have determined an ideal concentration of a substance. The problem with "determination of the concentration of a substance", is that it would generally be more qualitative rather than quantitative (that's my opinion, in any case). It might indeed be a good idea to have a look at IA samples from the IB, as @HappyIB:) said. They generally have examiner notes on them and can be of great use if you're not sure about what the IB expects. 1 Reply Link to post Share on other sites More sharing options...
