All lessons of this unit:    • JEE 2027 Chemistry | Unit 6 Equilibrium   How a common ion lowers the solubility of a sparingly soluble salt: s ≈ Ksp/c for an AB salt, the AB2 cases and why the squared ion matters most, why hydroxides and salts of weak acids dissolve more in acid while AgCl does not, and two solved JEE-style problems: AgCl in NaCl, and the salt of a weak acid in a pH 3 buffer. Chapters 0:00 Introduction 0:33 A common ion lowers the solubility 1:39 How much does the solubility fall? 3:00 The effect of pH: hydroxides 3:36 Salts of weak acids dissolve more in acid 4:29 Trap: which salt dissolves more in dilute HCl? 5:15 Example 1: solubility of AgCl in 0.10 M NaCl 6:14 Example 2: solubility of salt MA in a pH 3 buffer 7:31 Quick revision: common ion, hydroxides, weak acid salts A free JEE paper every day and a full JEE Main mock every Sunday: https://rankdeterminant.com/go/yt-dai...
