You could investigate how changing the atoms/groups attached to the central atom affects the shape/ bond angles of a molecule. 9. Will conclusion affect my point. Place a thermometer in the mouth of the can with a piece of cotton wool to prevent heat loss. As a potential extension to observing how the rate of reaction increases with temperature, you could find the activation energy for a particular reaction. I might just be wrong about how I'm actually supposed to use a database. For example, how does the bond enthalpy for the C-H bond vary as the length of the alkane increases? I just don't understand how I can use a database that is already focused on investigatingsomething and then use it to investigate something else???? You can post now and register later. See why 94% of our customers said they would be likely to recommend Alloy.ai. Databases There are many free, open-access databases which can be used for tasks ranging from simple data-finding to more authentic retrieval and analysis. Online Chemistry Tutor for A Level and IB | Dr Carl Thirsk. Within the finish, there are many colours produced depending on the paint company from 100 to 10000. If I do this experiment and I write it as a IA, Will I get higher points? Some anomers exist in an equilibrium between two forms which interconvert, for example glucose and lactose.

Compare the percentage of vitamin C in various brands of juice. Upload or insert images from URL. Can you please help? IB Survival LLC. Hello Astridde, glad you find the article useful. 49. In your Chemistry IA, being creative for your topic is not a very key criteria. As catalysts are involved in the rate-determining step of reactions, increasing the surface area of solid catalysts should also increase the rate of reaction. Acid-base titrations can also be used to assess the acidity of fermented foods and drinks such as sauerkraut and kombucha. Is the oxygen level in my local canal enough to satisfy the biological oxygen demand (BOD) for fish? Many students are unsure how to relate the IB chemistry topics to a real-world situation or problem that they can investigate. Determine the percentage of iron in an iron compound by a redox titration. It can be challenging because of the plethora of options students have. Investigate an equilibrium position and Le Chateliers principle spectroscopically. Students are expected to perform at least one exercise using a database in order to fulfil Aims 6 & 7 in the Guide. 35. Detailed instructions for the experiment can be found. www.thinkib.net. 21. The University subscribes to many other databases in other disciplines that may be of interest to you, see the A-Z Databases website. You could compare these two methods to see which gives more accurate results. Do expensive iron tablets contain more iron than cheaper vitamin tablets? Does the amount of aspirin in different brands accurately match the label? Phosphorus is needed by plants in order to produce amino acids and hence proteins. Administrative Links. Hi, I wanted to determine protein content of something over different cooking time but I did some research on the google and I found that proteins are not affected by heating. Proteins thermal denaturation using UV light. Provides access to scholarly journals and magazines covering the latest scientific developments. Typical solvents and solutes include water, seawater, heavy water, inorganic compounds, and a variety of organic compounds such as hydrocarbons, halogenated hydrocarbons, alcohols, acids, esters and nitrogen compounds. Determine the amount of copper in coins using colorimetric analysis. 11. 25. In my current life I teach exclusively diploma chemistry, so I get to mentor more student projects than probably anyone else. What is the pKa value for natural indicators obtained from peonies, poppies and red cabbage, determined using colorimetry? The IB chemistry IA is an investigative essay that seeks to explain the chemistry behind common real-world phenomena. Remember! A leading publisher of authoritative scientific information. The current programme reduced the overall component mark from 24% to 20%. Packed with tips and hints to help you avoid common errors, the guide will help keep your IA planning and execution on track. You could compare the experimental value with the stated value, and look at different brands of iron tablet. You could look at vitamin C tablets, different brands of orange juice or solid fruit and vegetables. 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. Attach a screen print of your Logical Design showing all relations fully expanded. With the cancellation of the May 2020 exams instead of the IA component counting for only 20% of the final mark it effectively became the main basis upon which grades were awarded. Reaxys -Web access to Beilstein/Gmelin and patent database; java structure editor; all users must create . The statements are deliberately broad and, if you decide to use any of these ideas, you should be as specific as you can. 33. What are good chemistry databases that can be used in the IA?

You could investigate why and how the value for a particular bond enthalpy changes depending on the overall molecule in which it is found. An important part of the course which requires 10hrs of work for both HL and SL student. Royal Society of Chemistry Resources, videos and screen experiments for teachers and students. Ptable is an interactive table of elements that allows users to alter temperature, see reactions, and find the electrons, isotopes and compounds for all of the elements. As long as you twist it in a way, present it in a way to get the correct impression from your teacher and the examiners. Investigate the effect of solvents in paper chromatography and thin layer chromatography. The IB should make IAs a part of only HL subjects. In 2010 Eugen Schwarz wrote a paper claiming that theoretical quantum mechanical calculations lead to the conclusion that the 3d level is lower in energy than the 4s level in transition elements. Uploaded by IB Screwed. Lots of people are anaemic and have to take iron tablets as a result. ChemSpider is a free chemical structure database providing fast text and structure search access to over 67 million structures from hundreds of data sources.

Title: The Effect of Changing Solutes on the Conductivity of a Solution Name: Kerry Jacobs Course: IB Chemistry Date: As biosciences become increasingly informatic in nature, knowing how to access, use and interpret is a valuable skill. My second worry is that the whole of the IA assessment has become a ticky box exercise involving passing through hoops that bear little relevance to how chemistry is normally reported. Which endothermic reactions are good for use in cooling packs, investigated with simple calorimetry? You could determine the pKa values and pH ranges of natural indicators using. By integrating and linking compounds from more than 400 data sources, it enables researchers to discover the most comprehensive view of freely available chemical data from a single online search.
