Compare High-Scoring vs. Flawed Chemistry RQs

Below are examples of evaluated RQs from recent Chemistry IAs. Review the strengths and weaknesses to understand the scoring criteria, and feel free to evaluate your own RQ using the form above.

10/10 Score
How does the type of dissolved salt (0.10 mol dm⁻³ NaCl, 0.10 mol dm⁻³ KCl, 0.10 mol dm⁻³ MgCl2) affect the electrical conductivity of aqueous solutions (conductivity in mS cm⁻¹) as measured with a calibrated conductivity meter at 25.0 °C?
Strengths:
3

Clear identification of three explicit salts to compare and a defined measurement (conductivity) with units.

Weaknesses:
0
1/10 Score
Is Chemistry important?
Strengths:
3

Clear topic area (chemistry as the focus).

Weaknesses:
6

Specify the independent and dependent variables in the question (e.g., change the phrasing to explicitly name IV and DV).

1/10 Score
Is Chemistry important?
Strengths:
2

The question is a complete sentence and would be understandable to readers.

Weaknesses:
7

Clarify the independent and dependent variables explicitly with a How does X affect Y? structure; for example: How does [IV] affect [DV]?

10/10 Score
How does the concentration of hydrogen peroxide (0.50%, 1.00%, 2.00%, 3.00% v/v) affect the initial rate of its decomposition (initial rate in mol L⁻¹ s⁻¹) as determined by measuring the decrease in H2O2 concentration using titration with 0.0200 M KMnO4?
Strengths:
4

Clear identification of multiple, explicit concentrations for the independent variable.

Weaknesses:
0

How to Evaluate Your Research Question

Simply choose your subject and enter your research question. Our evaluator will then analyze your question against the IB requirements and return a report with any issues or improvements you can make. Trained on thousands of IB RQs marked by official IB examiners, our evaluator is able to provide accurate and helpful feedback.

Frequently Asked Questions

Yes. Our Research Question Generator was trained on thousands of high-scoring IB exemplars, and the ideas it generates are designed to align with IB criteria so you can develop research questions that meet the standards.

Select your subject and category (IA or EE), optionally enter a few keywords or interests, then click Generate. The AI returns research question ideas tailored to your subject, which you can refine further with the tweak tools.

No. You can leave the keyword field blank for instant inspiration, or add a few words about your interests to get more targeted ideas.

Generated questions are starting points aligned with IB expectations. Similar research questions appear across cohorts—what matters is that your investigation or essay content is your own work.

The Research Question Evaluator was trained on thousands of research questions marked by IB-certified examiners. It evaluates your research question using the same IB criteria, helping you understand its strengths and areas for improvement.

Free users get a limited number of generations per week. Your limit resets weekly. Upgrade to Pro for higher limits and full access to Clastify AI tools.

Try combining a reaction system, a specific technique (such as titration, calorimetry, or spectroscopy), and the variable you plan to change. Name reagents when you can.

A chemically justified link between a controlled IV and a measurable DV (concentration, temperature, catalyst) that yields quantitative data.

The research question can state the relationship without listing every molarity; add concentration ranges in keywords if you want more lab-ready ideas.
