For solid reactants, increasing the surface area also increases the rate of reaction as more reacting particles are in contact with each other at any one time. Trying to choose a topic for your IB Chemistry IA can be difficult, especially when youre limited to a school laboratory and not much time! You should always get your IA checked out by your class teacher before you carry out any lab work to ensure that your experiment is safe. It scored 20/24 (which, according to the boundaries of the M20 session, was a 7). In contrast, dyes are either liquids or soluble, but can be converted to pigments by precipitation with a metallic salt. Although students are only supposed to deal with their own supervisor who is able to comment on the final draft there is nothing to stop students collaborating with other students and there are even websites now where IB teachers offer to help individual students with their IA for the payment of a fee. The statements are deliberately broad and, if you decide to use any of these ideas, you should be as specific as you can. For example, changing the temperature of the titration reaction, or heating to a higher heat or for a longer period of time in the thermal decomposition reaction.
