The student provides a detailed and focused description of the aim of the experiment, which is to investigate the temperature dependence of the equilibrium constant of the hexaaquocobalt(II)-tetrachlorocobalt(II) equilibrium. The student also provides relevant and exhaustive background information on the topic, including the laws of equilibria in the case of endothermic reactions and the Van't Hoff plot. The methodology chosen is appropriate and focused on answering the research question, including appropriate steps to assure the validity of the obtained results. The student also shows awareness of safety hazards and environmental issues that can arise during the experiment. However, ethical concerns are not addressed.
