kiyotter Posted January 6, 2021 Report Share Posted January 6, 2021 I was planning to do my HL chemistry database IA on the relationship between corrosion rate and pH level such as the difference between corrosion rate of steel when reacted with ocean water and rain water, but my teacher told me it is too simple and the answer is obvious. Are there any other factors I can or should add to my paper to make it complex enough? Or should I change my topic completely? Reply Link to post Share on other sites More sharing options...
