Main Page Google Drive Login Since access to school laboratories worldwide has been severely restricted or has been completely unavailable for long periods during the past year this has all changed. So far I've looked into medicinal chemistry and biochemistry and I want to do something related to the structure or drugs but do you think it would be easier if I switched to doing a database IA in organic chemistry (and look at solubility, melting pointetc)? Does cooking temperature affect the vitamin C content of kale as measured by iodometric titration? James awarded it a mark of 7/24 which I felt fairly reflected its worth according to the IB assessment criteria. Complexometric titration can also be used to measure the hardness of water, so you could look at how the hardness of different brands of mineral waters vary, or if the hardness varies with temperature or pH. VSEPR theory predicts the shape and bond angles of molecules based on the number of bonding and non-bonding pairs of electrons around the central atom. This is a list of ideas only, intended as a source of inspiration for students who are stuck for an idea. It scored 23/24 (which, according to the boundaries of the M20 session, was a 7).
