關於這個模擬實驗

Add sodium hydroxide to hydrochloric or acetic acid. Compare the titration curve, indicator colour and equivalence volume.

學生可以探索什麼

Predict the equivalence volume. Does a weak acid reach equivalence at pH 7?

學習目標

1Predict the equivalence volume. Does a weak acid reach equivalence at pH 7?

教師常問的問題

What assumptions does this simulation use?

Ideal dilute solutions at 25 °C. Acetic acid Ka = 1.8 × 10⁻⁵. Charge balance includes water; indicator colour is approximate. Endpoint and equivalence are different.
