Dissolved Oxygen in Water when adding Magnesium Chloride
Before I quit chemistry IB SL I had to do quite a few internal assessments. Since i am not in the program any loner, therefore my IA will not be turned it, I decided to put it to good use and upload it here. It was, according to my teacher, worth an IB 6. I received a 95% in the regular grading system. Students can feel free to use this idea, seeing as since it will not be turned into the IB, it will just disappear into my files on my laptop.
