EE Opinion

[Lynn Gweeny]

Hi,

I'd like an opinion on two ideas I have for a Chemistry Extended Essay: "How does the Kc of a hibiscus indicator change with temperature?" and "At what pH values do red, yellow and white hibiscus indicators change colours? What kind of titrations can they be used for?"

I'd like to know which of these topics would be simpler (I need to do a lot of reading and learning either way) and which one sounds original. I personally prefer the second one as I think its results will be more useful for real-world applications but I think I feel like its already been done.

Thanks in advance!
