For many experiments in chemistry, students will be required to have a complete written pre-lab activity before they are allowed to work on the experiment. In order to truly understand the laboratory activities and to be able to draw appropriate conclusions, a student must first carefully consider the procedures, concepts and reasons for doing the laboratory practices. Research has shown that students who have a written preparation for laboratory are safer, more efficient and have a better understanding of how the lab practices are connected to the regular chemistry classroom. In this laboratory manual, students are provided with analytical chemistry experiments including short introduction, purpose of each experiment, materials and apparatus required, procedures to carry on the experiments and data tables for recording the results. Sample lab reports and marking guide are also included in the manual since marking guides make explicit to the student the criteria against which their work will be assessed and they can be a comprehensive and efficient feedback tool
