C8. Acids, Bases, and Salts

Acid-Base Titration Simulator

Control the drip rate of a acid burette into an alkaline flask. Add indicators (phenolphthalein, methyl orange) and record pH curves to find the neutralization equivalence endpoint.

  • Describe pH changes during titration of strong/weak substances
  • Identify the titration end-point using indicators and graphical curves.

Mathematical Equations

Neutralization Equation
HCl + NaOH → NaCl + H2O
Concentration Formula
CA VA = CB VB

Inquiry Guide Sheet

1

Select Phenolphthalein indicator. Note the initial pink color of the sodium hydroxide base.

2

Add acid drops. Slow down near 25mL added and observe when the pink color vanishes (neutralization).

3

Plot the pH curve. Note the vertical region of the graph where equivalence occurs.
