IB Chemistry IA secondary data requirements

IB Chemistry IA Source Checker

Chemistry IA sources should support a chemically meaningful investigation with usable data, traceable conditions, uncertainty or limitations, and safe school-appropriate methods.

Chemistry IA

Source rules

What usually works for Chemistry IA

Usually strong

  • Student titration, kinetics, energetics, equilibrium, spectroscopy, or materials data with repeats and uncertainty.
  • Reliable chemical databases with units, conditions, and source provenance.
  • Peer-reviewed or official sources used for hazards, constants, or method justification.

Needs review

  • Database values with no temperature, pressure, units, or measurement context.
  • Hazardous methods that exceed school-lab safety constraints.
  • Pure recipe-style procedures copied without adaptation.

Avoid or replace

  • AI-generated chemical data or uncited property tables.
  • Unsafe synthesis, ingestion, uncontrolled reactions, or disposal issues.
  • Revision notes as evidence for experimental results.

Examples: strong, risky, weak

Strong

A student-collected rate dataset with controlled temperature, repeats, uncertainties, and cited safety data.

Review

A property database with values but incomplete experimental conditions.

Weak

A page explaining collision theory.

Where to find better Chemistry IA sources

If your current source gets a warning, do not just add more websites. Use searches that match the assessment rule and replace weak evidence with sources that can actually carry analysis.

Replacement moves

Replace ai-generated chemical data or uncited property tables. with student titration, kinetics, energetics, equilibrium, spectroscopy, or materials data with repeats and uncertainty..

Use database values with no temperature, pressure, units, or measurement context. only as context unless your teacher confirms they can carry evidence.

Add one source that gives direct evidence for the IA, not just general background.
