Here’s a explanation:
What is Precipitation Titration?
- Precipitation titration is a type of titration where a precipitate (solid) forms during the reaction.
- It is used to find the concentration of ions in a solution that form insoluble compounds when they react.
How It Works
- A titrant is added to a solution containing ions.
- The ions react and form an insoluble solid (precipitate).
- The point where precipitation is complete is called the equivalence point.
- An indicator or instrument shows when this point is reached.
Common Example
- Silver nitrate (AgNO₃) titrated with sodium chloride (NaCl).
- A white precipitate of silver chloride (AgCl) forms.
Uses
- To measure chloride, bromide, or iodide ions in a solution.
- Common in water analysis and pharmaceutical testing.
In short:
Precipitation titration involves forming a solid during the reaction to find how much of a substance is present in a solution.
