🚀 What You Will Learn Today:
1. The Concept of Equilibrium: Why rate of forward reaction = rate of backward reaction (Explained with my famous girl/boy analogy! 😂)
2. Electrolytes 101: Differentiating between Strong and Weak electrolytes based on conductivity.
3. Degree of Dissociation (alpha): Understanding what fraction of a substance actually breaks into ions.
4. Ostwald’s Dilution Law: Detailed derivation and why alpha increases as volume increases.
5. Limitations & Board Exams: Why this law fails for Strong Electrolytes and Saturated solutions.
