Sign in to playMeasure the pH of everyday liquids (battery acid, stomach acid, orange juice, coffee, milk, hand soap, drain cleaner…) with a draggable probe. Add solute or water from taps you hold open, or drain some solution and see that the pH stays the same. The Micro screen adds a graph of H₃O⁺, OH⁻ and H₂O concentrations on a log or linear scale; the Custom screen lets you set the pH directly or drag the ion concentration bars.
