Possible factors include the concentration of the alkali used, the temperature at which the reaction occurs or the length of the saponification reaction. Investigate an equilibrium position and Le Chateliers principle spectroscopically. You could even look at both the bond enthalpy and length to see how they change with each other. I've chosen a database topic, but I don't actually know where/how to find said databases.

If you are interested in medicinal chemistry, you could try synthesising. Strugglingfor IB Chemistry IA Ideas? It is a starting point for further research, not a list of off-the-shelf projects you can select from and take to your teacher. Investigate the effect of soil pH on the chlorophyll content in plant leaves. You could compare the experimental values with the actual values, or investigate how different cooking or preparation methods affect the amount of calories in a food. Does cooking time affect rate of chlorophyll degradation?
Labs and IA - DP CHEMISTRY - Google IB Chemistry IA Tips - Mindlab International This was partly to offset worries that it is difficult to ensure complete academic honesty.
The data collection effort has been conducted in an effort with the Materials Genome Initiative in an effort to increase materials discovery. Now many students are having to cope with an investigation based on secondary data. In your Chemistry IA, being creative for your topic is not a very key criteria. Many students are unsure how to relate the IB chemistry topics to a real-world situation or problem that they can investigate. Titrating the solution of unknown vitamin C content with iodine solution oxidises the vitamin C and reduces the iodine to iodide ions in a redox reaction. To help with this, Ive produced a list of chemistry IA ideas, together with some example Research Questions (RQ). 85% (130) 85% found this document useful (130 votes) 195K views. Is the rate of copper purification affected by the voltage? We provide the following chemistry databases: CSD - a Cambridge Structural Database system and related Mercury, ConQuest, SuperStar, IsoStar, and Mogul programs; RTAM - a bibliographic database of relativistic calculations on atoms and molecules; Free databases on the web. It also shows that the IB assessment criteria bear little relationship to the criteria used to judge the worth of a peer-reviewed report for publication in an internationally recognised academic chemistry journal. Chemistry Carl is a highly-qualified tutor, teacher and examiner with an outstanding track record of helping students to succeed. decomposition of sucrose into glucose and fructose. 41. Investigate the equivalence point of weak / strong acids and weak / strong bases. Ive given a weaker and a stronger example research question for each category, but be aware that the stronger research question is not necessarily a good research question! Search chemicals by name, molecular formula, structure, and other identifiers. The enthalpy of a specific bond is defined as the amount of energy required to break one mole of the bond in gaseous molecules, calculated as an average value over a range of different molecules. Is ease of thermal decomposition of metal carbonates related to their solubility? It often is the "make or break" so do ensure to take it seriously. Sitemap. If youre interested in getting additional support for your IA, we have a team of Chemistry tutors that can help you plan, structure and execute your assignment as well as help with your exams! Join.
