Please use the mark scheme I have uploaded to write this IA. The hypothesis, variables, materials, method, conclusion, and evaluation have already been written. Could you please write the introduction which should include personal interest (reason for choosing this topic which I have briefly described in the attached document) and background information on voltaic cells, how they work, oxidation, reduction, redox reactions, half equations, how electrons move in the cell? Please carry out the experiment with values for 3 trials and then data analysis which should include average voltage from the 3 trials, the absolute error of voltage, and percentage error of voltage. Present the values of average voltage on a line graph. Please make any improvements to the evaluation and control variables section.
