Acid-Base pH Lab

Acid-Base Chemistry – Free Interactive Online Lab

Acid-base chemistry underlies everything from digestion to industrial manufacturing. This free online simulator lets you mix acids and bases, observe proton transfer reactions, and watch pH shift in real time. Experiment with strong acids like HCl and weak acids like acetic acid to build intuition for Brønsted-Lowry theory.

What you can do in this simulation

• Select strong or weak acids and bases and observe dissociation differences
• Watch proton (H⁺) transfer animations between donor and acceptor species
• Track pH changes on a dynamic scale as concentrations change
• Compare conjugate acid-base pairs and understand their strength relationship
• Explore how dilution affects pH of strong vs. weak acid solutions

Concepts covered

Brønsted-Lowry theory · pH and pOH · dissociation constant Ka · conjugate pairs · proton transfer
