CHEM 1280: General Chemistry II Laboratory

This video discusses how the electronegativity of attached groups affects the strength of acids. Comparing pairs such as Chloroacetic vs Fluoroacetic and Acetic vs Nitroacetic acids, we highlight which is the stronger acid in each pair and why.

This video delves into the significance of electron configurations in understanding an atom's chemical behavior. It examines and corrects inaccuracies in the electron configurations of Aluminium (Al), Boron (B), and Fluorine (F). For instance, the electron configuration for Aluminium is initially presented with an incorrect number of electrons in the 2p subshell, stressing the importance of adhering to the rules of electron configuration for precise atomic representation.

Determine the molarity of a NaOH solution through titration with sulfurous acid. Starting with the ideal gas equation we derive the concentration of a 0.200L SO?-derived H?SO? solution. Concluding with a molarity of 1.64 M for NaOH using calculated values.

Explore why fluorine, with its seven valence electrons, doesn't form compounds like FH? or FCl?. Understand the role of VSEPR theory, atomic size, and electronegativity in limiting bond formation. Grasp the interplay of geometric challenges and electron repulsion in compound stability.
