CHEM 12220: General Chemistry

Exploring the titration of 25.00 mL of 0.08230 M KI with 0.05110 M AgNO3. This video breaks down the calculation process for the potential of silver ion at various volumes of added AgNO3: 39.00 mL equivalence point and 44.30 mL. With clear steps and using the solubility product constant understand how the potential of silver ion is determined for each scenario.

This video focuses on unit conversions and the practical use of conversion factors to translate quantities between different units. It provides clear examples of converting 70 kilograms to pounds, translating 14 billion years into seconds, changing the height of a basketball player from feet and inches to meters, and converting cubic meters to liters, illustrating the importance of this skill in various scientific and everyday scenarios.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

Learn the method to determine the count of SO? molecules, sulfur, and oxygen atoms from a given amount of sulfur dioxide (SO?). Understand the application of Avogadro's number in translating moles to molecules. Grasp key concepts of atomic structure and counting with hands-on examples.

Discover the contrasting processes of vaporization and condensation and their thermal nature. Understand why boiling is endothermic, absorbing heat, while condensation is exothermic, releasing heat, and how these processes impact ?H values.

This video delves into the fundamental concept of conjugate bases in the context of the Brønsted-Lowry theory of acids and bases, explaining how when acids donate protons, they transform into their respective conjugate bases. This understanding is exemplified through the specific reactions of various compounds, illustrating how each Brønsted acid, upon proton donation, gives rise to its corresponding conjugate base.
