Acids and Bases
Acids and bases show up everywhere, from lab reactions and buffer systems to digestion, cleaning products, and environmental chemistry. This topic hub builds from core ideas like pH and acid-base strength into the calculations and curves that chemists use every day. Start with a visual overview, practice with a calculator, then test your understanding in a titration lab.

Acids and Bases at a Glance
Get the big picture on acids, bases, pH, and neutralization before diving into calculations and equilibrium.
Open →pH, pOH & Acid-Base Calculator
Practice converting between pH, pOH, and acidity/basicity values to check your understanding quickly.
Open →Titration Lab
Run a virtual titration, watch the endpoint emerge, and connect solution behavior to the shape of the curve.
Open →Acid-Base Essentials
Keep these core ideas handy while you work through problems and lab activities.
- Strong vs. weak acids and bases: strength describes dissociation, not just concentration.
- Ka, Kb, Kw, and pH relationships connect equilibrium with acidity and basicity.
- Indicators, buffers, and titration endpoints help you identify what a solution is doing.

Common Questions
What is the difference between a strong acid and a weak acid?
A strong acid dissociates almost completely in water, while a weak acid only partially dissociates. That means strength is about how much ions form at equilibrium, not how concentrated the solution is.
Why is titration important in acid-base chemistry?
Titration helps you determine an unknown concentration and reveals key features like the equivalence point, endpoint, and buffer region. It is one of the best ways to connect acid-base theory with real measurements.
