Experience Interactive Chemistry Tutor with Diverse Expertise and Engaging Teaching Approach

The Student learned about buffer solutions, including their composition, how they resist pH changes, and how to calculate their pH using equilibrium principles and the Henderson-Hasselbalch equation. The Student practiced solving multi-part problems involving the addition of strong acids and bases to buffer solutions. The Tutor assigned homework problems and will send notes and additional questions via email. The next session was scheduled and will be confirmed.

The session covered coordination chemistry, including coordination number, geometry, and ligand types, followed by a discussion of acid-base chemistry, pH, Kw, Ka, Kb, and titration curves. The student practiced determining coordination numbers and geometries for various complexes and reviewed the definitions of acids and bases, as well as their relative strengths. The tutor will provide a list of strong and weak ligands and example problems on buffers for the next session.

The Tutor and Student discussed the properties of transition metals, including their ability to form complexes, exhibit colored ions, and have variable oxidation states. The Student learned about ligands, their role in complex formation, and the concept of d-d transitions. The Student was asked to send their curriculum to help guide future sessions and focus on specific questions or assignments.

During a recent lesson, an instructor and a student delved into Lewis structures, hybridization, bond angles, formal charges, valence bond theory, dipole moments, intermolecular forces, functional groups, and resonance structures. The learner, a student at Cal Poly Pomona, actively practiced identifying functional groups and drawing resonance structures, receiving valuable corrections and guidance. For continued practice, the instructor assigned additional resonance structure problems and arranged a follow-up lesson to discuss chapter 3.

The instructor and the student, a dedicated learner at Amberton University in Garland, reviewed organic chemistry concepts, including structural isomers, sigma and pi bonds, hybridization, and acidity/basicity. The student worked through integrated problems and identified factors affecting acidity and basicity. The instructor assigned practice questions from chapters one and two for the next lesson and planned to focus on chapter three on Monday.

Tanya led a chemistry lesson for an individual, a student at Golden West College in Huntington Beach, covering constitutional isomers, pKa values, and dissociation constants. They also delved into factors affecting anion stability, with the learner actively practicing how to identify stronger acids based on pKa values and anion stability. Their next lesson will continue with chapter 3, focusing on the stability of anionic species, and practice problems were assigned as homework.
