  1. Since this is an antilog equation, my teacher said that propagating concentration uncertainties from pH is beyond the scope of IB Chemistry syllabus so I would have to do another way. He said that I should " calculate half the range of the pH values for each variation." What does this mean???? For context, let's say my pH is 2.13 +/- 0.05 and my H+ concentration is 7.41E-3. How would I get the uncertainty of it? thank you so much 🙂
  2. Hey guys! I' doing HL chemistry and year 2 is about to start. We have to give the first draft of the IA in 2 weeks, and I think my topic is too simple and generic. My topic is to compare the effectiveness of 5 brands of antacid in curing an acidic stomach (which will be simulated by HCl). Do you think it looks okay, or is too simple?
