rraval10 Posted February 25, 2020 Report Share Posted February 25, 2020 Hi, I am deciding my topics for the extended essay in chemistry and was thinking of doing something around -: - The effect of pH on the hydrolysis of aspirin or - The most effective endothermic reactions to be used in instant cold packs. (currently used water and ammonia) Please give me feedback as to how I could improve my topics and any changes that I could make to make it more suitable to the real world.
