IA
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.
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:
Clear identification of three explicit salts to compare and a defined measurement (conductivity) with units.
Weaknesses:
Is Chemistry important?
Strengths:
Clear topic area (chemistry as the focus).
Weaknesses:
Specify the independent and dependent variables in the question (e.g., change the phrasing to explicitly name IV and DV).
Is Chemistry important?
Strengths:
The question is a complete sentence and would be understandable to readers.
Weaknesses:
Clarify the independent and dependent variables explicitly with a How does X affect Y? structure; for example: How does [IV] affect [DV]?
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:
Clear identification of multiple, explicit concentrations for the independent variable.
Weaknesses:
