Tues-Day 1
AP Chem - saw how acid-base titration/solution stoichiometry can be used to determine whether an acid is mono, di , or tri- protic. The other permutation is to take an acid of known empirical formula (but unknown elements other than H, of course) and use the titration data to determine its molar mass.
We then did one final assay/redox titration to determine the percent of a given element in a mixture/ore.
Bio - we reviewed the Biochem unit exam; significant improvement was shown on the scientific method answers! Keep up the good, detailed, and accurate work - those drawings definitely helped to structure your answers.
We still need to work on "relationship" between variables questions (as________ increases, the__________ increases/decreases/remains constant), AND on using the question KEYWORDS directly and appropriately in your answers.
