Ionic EquilibriumHandwritten Notes

Ionic Equilibrium is where most students lose marks in Class 11 — pH calculations, buffer action, salt hydrolysis, and Ksp problems all need careful approximations. These handwritten notes by Paaras Sir lay out each problem type with the standard shortcuts JEE and NEET expect.

Frequently Asked Questions

Are buffer-solution problems covered?+

Yes. Acidic and basic buffers are derived from Henderson–Hasselbalch with worked pH calculations on addition of acid/base — the exact pattern JEE Main asks every year.

Do the notes cover Ksp and selective precipitation?+

Yes. Ksp expressions, common-ion effect, and selective precipitation of metal sulfides/hydroxides are covered with worked examples — pair with the Ksp Calculator for practice.

Is salt hydrolysis treated for all four salt types?+

Yes — strong acid/strong base (no hydrolysis), strong acid/weak base, weak acid/strong base, and weak acid/weak base salts are each derived for pH and degree of hydrolysis.
