Experience Interactive Chemistry Tutor with Diverse Expertise and Engaging Teaching Approach

The Student and Tutor reviewed electrochemistry basics, including electrochemical cells, galvanic cells, electrode potential, cell potential, and the standard hydrogen electrode. The Student learned about cell representation and practiced identifying oxidation and reduction processes. The next session is scheduled to cover practice questions and fuel cells.

The session focused on solving chemistry problems related to chemical equilibrium, stoichiometry, and gas laws. The student practiced calculations involving Kc, molarity, the ideal gas law, and mole conversions. The tutor reviewed key formulas and concepts to aid problem-solving, with no specific homework assigned but reinforced understanding through practice.

The session covered chemical tests to differentiate between inorganic compounds and an in-depth review of the periodic trends and chemical properties of Period 3 elements. Reactions with water and oxygen were examined, along with discussions on the acidic/basic nature of resulting oxides. The tutor will email the student a file with slides summarizing the discussed material for review.

The Student and Tutor reviewed the properties of Group 7 elements (halogens), focusing on electronegativity, ionization energy, and oxidizing power. The Student learned about redox reactions, halide tests, and bleach production. The next session will cover Period 3 elements, and the Student was asked to send questions in advance.

The Tutor and Student discussed Carbon-13 NMR spectroscopy, focusing on the principles behind signal generation and how to determine the number of signals based on a molecule's structure. The Student practiced identifying unique carbon environments in various compounds and predicting the corresponding NMR spectra. Additionally, the Tutor explained the experimental process of titration, particularly the investigation of pH changes during the reaction of weak acids with strong bases, including plotting calibration curves. The Student was assigned homework from the AQA chemistry A-level NMR question bank.

The Student reviewed proton NMR spectroscopy, focusing on interpreting NMR spectra to deduce molecular structures. The session involved working through example problems to understand how chemical shifts, integration, and signal splitting patterns provide information about different proton environments. The Tutor assigned practice questions to reinforce the concepts learned, and the next session will cover carbon NMR.
