The student provides a focused and detailed description of the aim of the experiment, which is to determine the enthalpy of the reaction between H2O4 and NaOH, (NH4)2SO4 and NaOH, and H2SO4 and NH3 and to subsequently examine Hess' Law. However, the Internal Assessment lacks a research question and background information. The chemistry of the experiment is not explained well enough for the reader to fully and easily understand it without the need for rereading. Furthermore, the methodology of the investigation is not appropriate to the topic, and there is no evidence of the student being focused on addressing the aim of the experiment as no variables were stated. The Internal Assessment also lacks control variables and safety hazards, ethical concerns and environmental issues were not stated.
