The student provides a detailed description of the aim of the experiment, which is to investigate how the ionic charge of cations across period 3 affects the conductivity of the salt solutions within which they are found. The background information section is informative and relevant. The student explains the chemistry involved in the experiment clearly. The methodology is appropriate, focused and includes appropriate steps to assure the validity of the obtained results. The student also shows full awareness of safety and environmental hazards that can arise during the experiment. However, there is no mention of ethical concerns.
