Buffer Solutions Buffer Action Mnemonics
Buffer solution
. Definition of Buffer Solution
Mnemonic:
“Buffer Builds Balance!”
- Buffer → Builds
- Balance → Maintains pH stability
Helps you recall:
A buffer solution resists changes in pH when small amounts of acid or base are added.
🧪 2. Types of Buffers
Mnemonic:
“SAB: Strong And Balanced”
- S: Salt
- A: Acid (weak) → for acidic buffer
- B: Base (weak) → for basic buffer
Apply it like this:
- Acidic buffer → Weak acid + its salt with strong base
(e.g., CH₃COOH + CH₃COONa) - Basic buffer → Weak base + its salt with strong acid
(e.g., NHâ‚„OH + NHâ‚„Cl)
3. Working Mechanism of Buffer
🔑 Mnemonic:
“Add Acid? Base Blocks it!”
“Add Base? Acid Attacks it!”
Helps you remember how buffers resist pH change:
- When acid is added → base part of buffer neutralizes it
- When base is added → acid part of buffer neutralizes it
4. Buffer Equation (Henderson-Hasselbalch for pH)
Mnemonic:
“pH = pKa + Salt over Acid (log)”
→ pH = pKa + log ([Salt]/[Acid])
✅ Helps you remember the formula for acidic buffer
5. Real-Life Applications Mnemonic
🔑 Mnemonic:
“BLOOD”
- Blood (main example)
- Lab solutions
- Organisms’ fluids
- Over-the-counter meds (antacids)
- Drugs (formulation stability)
