Neutralization Reactions
by Anonymous
Add acid and base particles to compare the H⁺ and OH⁻ released, then read the solution's nature from indicator colors and the ions left over after neutralization.

About this app
Neutralization Reactions is an interactive middle school science app about acids, bases, indicators, and neutralization. Explore how hydrochloric acid, sulfuric acid, sodium hydroxide, and calcium hydroxide release different numbers of H⁺ or OH⁻ ions per particle. Then test indicator colors in acidic, neutral, and basic solutions and pair H⁺ with OH⁻ to see how water forms and how leftover ions determine the mixture.
Use cases
- Middle school students learning acids and bases
- Teachers demonstrating ion production and neutralization
- Learners comparing common indicators
- Science classes practicing acidic, neutral, and basic mixtures
Features
- Select four substances and vary the number of particles dissolved
- Visualize the H⁺ or OH⁻ ions released by each particle
- Test litmus, phenolphthalein, and BTB in three solution types
- Compare which solution types each indicator can distinguish
- Choose H⁺ and OH⁻ amounts and calculate water formed and ions left over
- Work through guided challenges with reset and next controls
