Study Notes
Purpose of Titration
- Titration of a strong acid with a strong base aims to determine the concentration of the acid through neutralization, allowing for quantitative analysis of acid-base reactions.
Endpoint Indicators
- The endpoint of a strong acid-strong base titration is indicated by a distinct color change of an acid-base indicator, signaling that neutralization has occurred.
Equivalence Point Expectations
- At the equivalence point during the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH), the moles of acid equal the moles of base, resulting in a neutral solution.
pH at Equivalence Point
- The typical pH value at the equivalence point of a strong acid-strong base titration is around 7, indicating a neutral solution.
Role of Phenolphthalein Indicator
- Phenolphthalein serves as an indicator in strong acid-strong base titrations, changing color from colorless in acidic solutions to pink in basic solutions, thus visually representing the completion of the titration.
