Recent Tutoring Session Reviews
"We covered oxidation state number half reactions. The student has an A in the class. She has completed all the questions I provided, as well as her HW. She will do fine on the quiz."
"Today we went over some very basic chemistry fundamentals. We worked through about half of the student's homework problems for the week. We examined the periodic table and how it is laid out, the properties of various groupings, and how to identify information about a given element. We went over protons, neutrons, and electrons and talked about the electron shells and valence electrons. We also started going over ions and ionic compounds. We talked about cations and anions, how to identify the charges of an ion, and the basic naming rules for cations and anions. Identifying the charges on ions in an ionic compound was also initially tricky for her, but with practice she got much better."
"The student has a Unit 12 test on Thursday on acids and bases. She had flagged specific worksheet problems, and so we addressed those first, including problems on neutralization, titration, dissociation, and calculating pH. We came up with an approach to dissociation and calculating pH. Furthermore, we reviewed precipitation reactions, writing complete ionic equations, and writing net ionic equations. Finally, we reviewed conjugate acids and bases through concepts and practice problems. I followed up our session with an email providing additional information on titration, including links to relevant videos on weak acid titration, half equivalence point, titration roundup, and acid base titration. I encouraged her to make flashcards of the common polyatomic ions and solubility rules before the test, as these concepts are both relevant to this unit and the upcoming final exam."
