Chloride ion estimation is which type of titrationa.Complexometric titrationb.Argentometry/precipitation titrationc.redox titrationd.acid-base titration

To determine the type of titration used for chloride ion estimation, let's analyze the options provided:

1. Complexometric Titration: This type of titration involves the formation of a complex between the analyte and a titrant, generally used for metal ions rather than halides like chloride.

2. Argentometry/Precipitation Titration: This method specifically involves the use of silver ions (Ag⁺) to precipitate chloride ions (Cl⁻) as silver chloride (AgCl). It's a classic method for determining chloride concentration.

3. Redox Titration: This involves the transfer of electrons between the titrant and analyte, usually applicable for oxidizing and reducing agents, not typically for simple ionic solutions like chloride.

4. Acid-Base Titration: This titration measures the reaction between an acid and a base, and is not applicable for chloride ion determination.

Final Answer

The correct answer is b. Argentometry/precipitation titration.
