please make sure when you do my background please make sure that the sources are cited underneath after you are finished writing the background. I would like for this whole thing to be revised so for the concentrations don’t make them percentages, and the methods cant be vague. This is for IB so I would like someone is familiar with the IB curriculum. For general procedures, please explain how I will use the materials to do my experiment better. Also please put me my name and period and ID number exactly as it is before.
