What is Fajan's method of argentometric titration?
Fajan's method of argentometric titration involves the use of potassium chromate as an indicator to detect the end point of a titration between silver ions and chloride ions. The indicator changes color from yellow to red when all the chloride ions have reacted with the silver ions, marking the end point of the titration.
Why you do not use H2SO4 in iodometric titration?
Using H2SO4 in iodometric titration can lead to the formation of H2O2, which interferes with the reaction. It can also oxidize iodide ions prematurely, affecting the accuracy of the titration. Therefore, a different acid like HCl is typically used in iodometric titration.
What do you mean by argentometric titration?
Argentometric comes from the Latin word ''argentum''which means silver. Argentometric titrations are precipitation titrations based on the use of silver nitrate as the precipitating agent.For example in titrations of halide ions,divalent anions,mercaptans(Ag2S),Fatty acids etc. By Lukato Simon Makerere University Kampala,Uganda Tel.0782528726.

Why you use iodine in iodometric titration?
Iodine is used in iodometric titration as the titrant because it can easily react with reducing agents to form iodide ions. Its reaction with reducing agents leads to a change in color, making it useful for visual endpoint detection. This allows for the determination of the concentration of the reducing agent being analyzed in the titration process.
How could you detect the presence of I ion?
One common method to detect the presence of Iodide ions (I-) is to use the Silver Nitrate test. When Silver Nitrate solution reacts with Iodide ions, a yellow precipitate of Silver Iodide is formed. This precipitate is a visual indicator that Iodide ions are present in the solution.

Why is argentrometric method called as a mohr method?
The argentometric method is called the Mohr method because it was developed by the German chemist Karl Friedrich Mohr in the 19th century. This titration technique involves the use of silver nitrate as a titrant and is specifically used for the determination of chloride ions in a solution. The method is characterized by the formation of a colored precipitate (silver chromate) at the endpoint, which occurs when all chloride ions have reacted, indicating the completion of the titration.

What is the name of the ionic compound LiI?
The name of the ionic compound LiI is lithium iodide.
What is iodometry and iodimetry titration?
Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.
Difference between precipitation titration and complexometric titration?
In precipitation titration, the formation of a solid precipitate is used to determine the endpoint of the titration, while in complexometric titration, a complex formation reaction is used to determine the endpoint. Precipitation titration is often used for specific ion determinations, while complexometric titration is used for determining metal ions by forming stable complexes with titrant.
How do you get accurate titration value?
To get an accurate titration value, ensure that all reagents are standardized and accurately measured, use an appropriate indicator, perform the titration slowly and carefully, and repeat the titration for consistency. Calibration and proper maintenance of equipment are also important for accuracy.
Companies that use titration?
Companies that use titration include pharmaceutical companies for drug development and quality control, food and beverage companies for testing acidity levels, and environmental agencies for monitoring water quality. Additionally, chemical manufacturing companies use titration for analyzing the composition of their products.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.
