The student clearly stated the independent and dependent variables in the research question, identifying the ethanoate buffer concentration as the independent variable and the buffering capacity as the dependent variable. The methodology was well described, including the titration analysis method, and the background theory relevant to the research question was comprehensive. However, the student did not provide a clear explanation of the techniques used for measuring the variables, particularly the preparation of the ethanoate buffer. Nevertheless, the student successfully addressed safety, ethical, and environmental concerns, and the methodology was sufficiently detailed to allow for reproducibility without any irrelevant or repetitive information.
