Chemistry EE Research Question

[wookie2187]

So I was wondering if all Chemistry EE questions have to be in the form What(independent variable) affects what(dependent variable)? Can it simply be something like' an investigation into the properties of a substance'? or modelling so and so?

This is from the EE guide, but the point is that you are really focused on finding something out with your investigation and not explore a topic, which is why a question is a good idea, sort of guides you to find out the answer.

Criterion A: research question
Many research questions can be formulated as an actual question or questions. A typical example is: “What gas is
evolved when zinc is added to copper (II) sulfate solution and what factors affect its formation?” . However, in
chemistry extended essays it is perfectly reasonable to formulate the research question as a statement or as a
hypothesis rather than an actual question. “An analysis of the amount of aluminium in three different brands of
underarm deodorant by visible spectroscopy” and “The kinetics of oxidation of iodide ions with hydrogen peroxide
in acidic solutions” are two such examples where a statement rather than a question is appropriate. Whichever way
it is formulated, it should be identified clearly as the research question and set out prominently in the introduction.
