Acids & Bases

Follow proton transfer through neutralization, pH, and buffering.

Follow the cause1 / 3

A proton is transferred. A Brønsted acid donates H+ while a base accepts it; the paired transfer preserves the proton count.

Focus the idea
Acids and bases exchange protonsThe model contains 5 acid units and 2 base units. 2.0 are neutralized, the buffer strength is 0.2, and the resulting pH is 2.3.acidbaseH⁺neutralized 2.0 · buffer 0.2

2.0 units cancel through proton transfer; the excess determines the direction of pH.

This is a relative teaching model: pH is logarithmic in real solutions, while the stage emphasizes proton transfer, neutralization, and buffering before full equilibrium calculations.
