pH Scale

pH Scale

pH Value Simulation

Description

Lemon juice is sour and soapy water is basic, but a textbook's colored bar says little about the hydrogen ion concentration behind pH. pH Scale offers coffee, blood, hand soap, hydrochloric acid and more, and dipping the probe gives a reading while adding water shows dilution in action.

A molecular view shows the counts of hydrogen and hydroxide ions, making it clear that one pH unit means a tenfold concentration change.

Features



Probe readings: Put the probe into any solution and read the pH live.

Dilute and mix: Add water or another solution and watch the value change.

Molecular view: See ion counts to understand the logarithmic scale.
