pH Scale

This interactive simulator explores pH Scale in Chemistry. Slider from 0 to 14 with common substances and color indicators. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Suited to beginners and first exposure to the topic. Typical context: Chemistry.

How it works

The **pH** scale measures hydrogen-ion activity in water-based solutions. **pH 7** is neutral at 25 °C. Lower pH means **more acidic** (higher [H⁺]); higher pH means **more basic**. Colors mimic a **universal indicator** — real lab measurements use calibrated probes or dyes.

Key equations

pH = −log₁₀[H⁺]  ·  pOH = −log₁₀[OH⁻]  ·  pH + pOH ≈ 14
