How good is this IA topic? "Investigating the effect of increasing concentration on the rate of reaction between sulfuric/hydrochloric acid and calcium carbonate." Are there any possible improvements to this topic? Like is this possible to do? If not, what are some changes I could make?
How many marks are uncertainties worth in the chemistry ia? If I were to not include them at all how many marks would I lose? If I did them incorrectly how many marks would I lose?
Hello! I wanted to compare natural pH indicators (ex, red cabbage and beets) with the standard ones. I was thinking of just doing pH titrations to compare the results of the natural vs standard. Along with that, I was going to produce the pH curves and calculate the pKa value as well as the equivalence points. Is this good enough for an IA? Should I add anything?
