The video offers an insightful look into the orthorhombic unit cell, a unique crystal lattice structure. By exploring nickel sulfate's unit cell and its specific dimensions, we determine both the number of formula units and the density of this crystalline structure.
Lattice Energy: Always Positive; Hydration Energy: Always Negative
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video we clarify why lattice energy in solids is always a positive value due to the energy needed to separate ions making it an endothermic process. On the flip side hydration energy is always negative as it releases heat when ions dissolve in water making it an exothermic reaction. We use sodium chloride as a real-world example to illustrate these crucial thermodynamic concepts
Conjugate Bases of Brønsted Acids: Formulas and Descriptions
Want To Learn More? To watch the entire video and ALL of the videos in the series:
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.
