Liv S. Sletten Posted December 29, 2015 Report Share Posted December 29, 2015 Im planning my chemistry (2016 syllabus) Im very interested in environmental chemistry, and since the new syllabus is going to put a lot of emphasis on personal engagement, i thought it was important to think about that. I want to investigate the effect of increasing ocean salinity on the concentration of dissolved oxygen. So my plan is to prepare different solutions of different salinity ==> here is some chemistry maths..Then Im planning on measuring the oxygen content using a sensor. I have a hypothesis, backed up by solubility theory which i can support or reject. I can prove a trend or disprove a trend. HOWEVER, is the design of my experiment TOO simple? I am very concerned about this, but similar, I know that i can get quantitative results. I can calculate uncertainties, errors etc. Qualitative results.. not much, but I can always comment on what i observe about the different saline solutions. I know that i could use the Wrinkler method to determine oxygen concentration as well, but I REALLY dont want to spent a lot of time on this because I did my EE in chemistr and im HL student, so i got enough alreaady now. Please I hope you can help Reply Link to post Share on other sites More sharing options...
