Hello, I wanted to do an IA on enthalpy of displacement of different metals and to somehow connect it to electrode potential, but im not sure how i could connect the two
Electrode potential is a physical Property and displacement is chemical. This is why Li is at top of reduction potentials not K. I’d think about narrowing the focus perhaps
hello! For the chemistry ia, i wanted to compare the enthalpy of different food scraps (enthalpy as in, it being a form of fuel, so basically, looking for which type of food scrap would give me the most energy for the same amount of mass. Food scraps such as, rinds, peels, eggshells, stems etc), and since im a higher level student, i wanted to connect it to entropy , but im not sure how, could you please provide me with some feed back? I would greatly appreciate it!! Thankyou!!
Hey, I was about to do my IA on the effect the degree of saturation of vegetable oils had on calories or their enthalpy of combustion but I figured out it was too dangerous because the flame the combustion of a vegetable oil would produce would be too big. Now I have to investigate the effect the structure of different alcohols has on the enthalpy of combustion, can I still aim for a 7 with this question?
It's not what you do it's the way that you do it ! Structure ( substitution ) on enthalpy could score well but its is easy to see how it could also score poorly.
Hi, I am doing my EE in chemistry and I wanted to ask you what you think about this reserach question: "How does pH affect the formation of ferric hexaaqua complexes [Fe(H2O)6]3+ when FeCl3·6H2O powder is dissolved in water at varying concentrations?"
@@JamesMidgleyChem Maybe it would actually make more sense if it was the other way around? Like how does changing the concentration affect the pH? But then it might be too simple for an EE, I don't know. Also the concentration of what? The initial FeCl3? The hexaaqua iron complex, or the other dissociation complexes? I'm not sure what it for the best.
Its not bad ! It can score well if done well. Just bear in mind moderators are human beings and are ultra congiscent of common pitfalls and erros with this experiment. Best of luck ! Mr M
Hello Mr M 4 Chem, would "Determining the amount of phosphoric acid in different samples of sodas and comparing the effect on their shelf life." be a good IA topic?
Good Day Sir!! I desperately need help eek! For my chem IA i wanted to look at the effect of temp on the rate constant of the iodine clock reaction and find the activation energy as well. one issue though; is it right to find the activation energy of such a reaction? the reaction is a complex multi-step reaction though so how do we know which step we're finding the activation energy of? or is it the overall activation energy? I'm so confused reg. the activation energy aspect and was even considering switching to the iodination of propanone but since that's a mandatory lab, I'm have my doubts. can you pleasseeee help me!!
stay away from mandatory labs. Calculating Ea by varying T is popular and can score well if done well. Crystal violet with NaOH or Briggs Rauscher are good systems to study
Hi I’m struggling with my IA topic and wanted something easy to understand but not too simple. I had an idea for how temperature of an aluminum sulfate solution effects water purity. would be okay?? Or is it too simple and predictable another idea was in regards to skin care and cosmetics how does concentration of sodium chloride in a solution effect it’s ph (hoping that my perspective from skin care makes it more unique) please let me know which one would be a better option of alterations to either or none at all! thank you
Id caution against both as there is an absence of data processing in both RQs. Have a look at my chem collective/ WebMO / chemreax videos as a straight forward method to maximise chances of earning high marks.
Hello Mr. M I am doing a database chem IA on finding the relationship between the lattice energy and electronegativity of various chemical compounds, but I having trouble making experimental procedures. Do you have any advice on how to do this?
State why you chose the IV and DV range. Explain what databases you used and did not use. Give a thorough chemistry account of the science which led to your RQ
@@JamesMidgleyChem Thank you for the reply! I also have another question about my IA: do you think it would be better to use the born-lande equation or the born-haver cycle to calculate lattice energy using a database? Also is it correct to say they electronegativity is the DV i am investigating? My idea is to calculate the lattice energy then compare it to the known electronegativity of compounds.
@@kinu3690 Hi - sorry calc of LE is great way forward / electronegativity perhaps not as can be read direct from your data booklet / need to focus your RQ further
Both are problematic. How would rate be validated ? Rust particles are tiny and difficult to ascertain what oxide or hydroxide is formed. Specificity is an often overlooked issues.
Hi Mr. M, Is it appropriate in a chemistry ia to investigate the effect of temperature on Ksp through electrochemical methods (Nernst equation to be precise)? I wanted to do this because I have read that for salts with very small Ksp using an electrochemical cell's potential data yields better results than other methods (titration etc.).
Hi Mr. M, I've sent you an email, though I think the easiest way to reach you is through the comments. My IA idea is how salt concnetration affects rust production. I left nails in salt water solution for 2 days. To measure the amount of iron oxide produced I am using a colourimeter. Though, I am putting the agitated/suspended precipitate of iron oxide directly in the colorimeter, is this reasonable/accurate to do? I am using a colorimeter as the orange/red color will be stronger with more iron oxide, therefore it can present an idea of the amount of iron oxide precipitate produced. Therefore in my conclusion is it reasonable for me to plot the concentration of salt against absorbance or transmittance even though neither have units? This investigation is therefore really a rate of reaction experiment, does it matter if I do not find a rate rather just investigate how the concentration of salt affects absorption, as I cannot create a standard curve with iron nails in same condition? Or is it possible to create a standard curve with iron oxide powder, even though this standard is not done with nails? Any help would be great, thanks sm,
As always check the extremes of the range of your IV - if this gives a relationship with consinderation of uncertainty then all good. There is however a clear safety risk here and i would strongly advise agains hot acids or alkalis
Hi Mr.M, I have been trying to reach you through email however youtube does not allow me to access your email account. I was hoping to meet with you regarding an Ia question as I our research questions are due. I originally wanted to do something in regards of asprin reactions or enthalpy of combustion of food such as yeast in bread. However my teacher advised against both ideas and suggested that I do activation energy of iodination of acetone. I was going to ask how do you feel about this topic in regards of it being able to score highly on an Ia and the process itself. Thanks again and I was going to ask if we can further connect through email as-well.
Hello Mr. M I was doing my Ia on the percentage of CaCo3 in various types eggschells. I didn't know that was a mandatory experiment, we didn't do such an experiment in school. Do I have to change it or is there any way I can alter it to make it a proper IA? (I'm taking Sl)
"Vit C" please no - I concur!
Word up ⬆️ 👏
i aboslutely love this man

investigating the inverse relationship between temperature and pH in an acidic and basic aqueous solution
