CSIR-NET Chemical Sciences revision note · 13 sections · about 772 words

Exam-focused revision notes on Ionic Equilibria for CSIR-NET Chemical Sciences, GATE Chemistry and IIT-JAM — the core concepts, the formulas worth memorising, the traps that cost marks, and a quick-recall table.

The core idea

Ionic equilibria is the acid–base and solubility toolkit: Ka, Kb, Kw, Ksp, the pH scale, buffers, hydrolysis and titration curves. Almost every question is a short calculation from one of these relations.
