A.1Topic communication and explanation
Excellent
A.2Research question formulation and focus
Excellent
A.3Research methodology
Good
Criteria Feedback
- Research question is clearly stated, well focused, and effectively connected throughout the report
- Topic is communicated accurately with clear purpose and focus in background and abstract
- Use of logistic regression for probe saturation modeling is well justified and aligned to the RQ
- Historical anecdote on Priestley is engaging but tangential and dilutes focus
- Controlled‐variables section omits headspace volume and probe saturation range control
- Methodology recognises probe saturation but does not fully mitigate it, risking systematic bias

B.1Application of source material
Good
B.2Subject knowledge
Good
B.3Use of terminology and concepts
Good
Criteria Feedback
- Sources (textbooks, primary articles, databases) are relevant and mostly well integrated to support hypotheses
- Subject knowledge is clear and coherent, with effective use of chemical concepts (Henry’s law, Le Châtelier’s principle)
- Terminology such as ‘acid dissociation constant’, ‘instantaneous rate’, and proper units are generally accurate
- Application of source material is sometimes descriptive rather than analytical, with large uncritical blocks of text
- Occasional misconceptions (pH–solubility relationships without buffer discussion) and inconsistent units (ppm vs mol dm⁻³)
- Formatting errors in logistic equations and pH calculations indicate lapses in precision
