CHEM 221: Elementary Spoken Mandarin I

Discover the difference between strong and weak electrolytes by understanding their ionization in water. Using nitrous acid and nitric acid as examples, this video provides chemical equations that visually distinguish the ionization behavior of these electrolytes.

Discover the importance of calculating percent error to assess the precision of experiments. Through real-world examples like measuring alcohol's density and the mass of gold, learn how this value offers insights into measurement accuracy and ways to refine methods.

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.

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.

Discover how to calculate the vapor pressure of a glycerin solution when mixed with water at a specific temperature. A valuable chemistry lesson.
