AP Chemistry / Unit 4: Chemical Reactions
4.6 Introduction to Titration
Notes
A titration adds a solution of known concentration (titrant) to find the unknown amount of analyte.
- At the equivalence point, moles react in the equation's ratio.
- Indicators change color near the endpoint.
Practice
25.0 mL of HCl is neutralized by 20.0 mL of 0.10 M NaOH. [HCl] is:
$0.10(20.0)=M(25.0)$.
At the equivalence point of HCl with NaOH:
Stoichiometric amounts.
An indicator's job:
Visual signal.
