Ionic Equilibria — Class 12 Maharashtra HSC Chemistry revision notes
A 4-page visual revision sheet for Ionic Equilibria, written for Class 12 Maharashtra HSC Chemistry. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Ionic Equilibria sheet covers
- Strong vs Weak Electrolytes
- Strong electrolyte
- Weak electrolyte
- Degree of Dissociation
- fraction of total moles that dissociates at equilibrium
- percent dissociation
- equilibrium concentration of either ion for a 1:1 electrolyte, initial concentration c
- Acids, Bases and pH
- Arrhenius
- Bronsted-Lowry
- Lewis
- Amphoteric Nature of Water
- Ionisation Constants
- acid dissociation constant, HA to H+ and A-
- base dissociation constant, BOH to B+ and OH-
- Ostwald's Dilution Law
- exact form, weak acid, initial concentration c
- for a weak acid α is small, so 1-α ≈ 1
- degree of dissociation follows
- the same relations hold for a weak base, with K_b
- pH of a weak acid from Ka
- Autoionization of Water and Kw
- self ionisation of water
- ionic product of water
- at 298 K
- pH and pOH
- pH
- pOH
- relationship, from K_w at 298 K
- Acidity, Basicity and Neutrality
- Hydrolysis of Salts
- Types of Salt Hydrolysis
- Strong acid, strong base
- Strong acid, weak base
- Weak acid, strong base
- Weak acid, weak base
- Buffer Solutions
- Henderson-Hasselbalch Equation
- pH of an acidic buffer
- pOH of a basic buffer
- the p-scale definitions used above
- Buffer Action, Properties and Applications
- Solubility Product
- general sparingly soluble salt
- in terms of molar solubility S
- Condition of Precipitation
- Common Ion Effect
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Chemistry chapter by chapter against your real exam dates and free hours, and when the plan reaches Ionic Equilibria the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
