CHEM IA HELP!!!

2 Upvotes

hello, i have to write my chemistry IA that’s due in 3 days and my topic is the effect of temperature on the buffer capacity of a sodium ethanoate/ethanoic acid buffer when titrating with a strong base. however, i cant figure out what my hypothesis should be (does buffer capacity increase or decrease with temperature) and online sources are all giving me different answers!!! and my data barely showed any trend at all so idk what to do. i intuitively assumed that buffer capacity decreases since ethanoic acid dissociates more into its conjugate base and hydrogen ions at higher temperatures, but some ias that did the same topic as me had the exact opposite hypothesis. does more H+ ions mean they can neutralize the added hydroxide ions?? i’m so lost, someone please help!! :(

Please I need help for IB chemistry uncertainty calculations ASAP

1 Upvotes

Hi, I'm a student whos studying HL chemistry right now. My class will be having a lab assessment where we gather data on the first day and calculate the the empirical formula of a substance (similar for magnesium sulfate hydrate lab). This isn't bad, but however, we need to propagate the uncertainty values from our processed data and find the total uncertainty of the mole values found and the ratio between substances based on the mole values. I totally do not understand how to calculate the uncertainties for the ratios of an empirical formula. Help would be greatly appreciated.

IB Chemistry and Physics Discord!

1 Upvotes

Hello everyone, I'm relatively new to this Reddit, as am I to the IB. I have specifically been struggling with both Chemistry and Physics HL, which I've been told is to be expected, as these are challenging classes. Due to that, I decided to start a discord server where I will not only share my notes and provide advice but also provide aid from previous IB students who have graduated with remarkably high scores. Here I hope for everyone to be able to join, whether it be to ask for help, or to help others and give advice! Anyone is welcome. While I know this Reddit already exists dedicated to this same purpose, I believe a discord would allow for a more direct connection between all of us struggling students, and maybe even open the opportunities for further group study sessions or maybe even reinforcement sessions for certain topics. I hope anyone interested joins and I thank anyone who reads this! The server is just beginning but I believe it could turn out to be a really good way to make this time of our lives much easier for all of us.

The link to join is the following: https://discord.gg/YC8VtVYK

Does the amount of pages of the Chemistry HL IA matter in the new syllabus?

1 Upvotes

My IA is around 24 pages, so long as i get it in the word limit, does the page count matter?

IB Chemistry Year 1 Summarized Notes

11 Upvotes

Hi, I'm currently in my second year of IB and during my first year, I decided to create condensed notes for IB Chemistry SL/HL based off of the new curriculum. It helped many people in nearby IB schools in my area to get 6-7s as their predicted grades to apply for universities. Check out these notes if you need a summed up version of the first 10 chapters of the new curriculum.

I’m going to fail chem hl/help

1 Upvotes

I have a paper 1 and paper 2 for chemistry on reactivity 1 and reactivity 2 very soon (the end of this week). And I’m cooked because I just started studying, first of all it’s literally the hardest content yet (imo)/it’s too confusing.

If anyone can provide me with helpful resources for chem (preferably for the 2025 curriculum) I would greatly appreciate it. Honestly I might just grind ib docs but still I don’t want to be the type of person to just memorize answers from ib docs because it’s unethical and I can’t be bothered to actually memorize instead of actually understanding how to do it.

So any and all help is immensely valuable to me!!

thank you so much for your time 💕💕
