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 do we carryout blank titration in argentometric titration?
Blank titration is carried out in argentometric titration to account for any impurities or contaminants present in the reagents used. By measuring the volume of titrant required to reach the endpoint in the blank titration, this value can be subtracted from the volume used in the actual titration to determine the accurate amount of titrant required to react with the analyte.
Why must the titrations in fajans method be carried quick and iniffuse ligt?
In Fajans method, quick titration is necessary to minimize the effect of background diffusion that could affect the accuracy of the endpoint determination. Using diffuse light helps to prevent any color changes from being obscured, making it easier to visually detect the endpoint in the titration process.
Why pottasium chromate is used as indicator in argentometric titration?
Potassium chromate is used as an indicator in argentometric titrations because it forms a red precipitate (silver chromate) in the presence of excess silver ions. This color change signals the end point of the titration, where all the chloride ions have reacted with silver ions. This makes it easy to visually detect when the reaction is complete.
Why silver nitrate is used in argentometric titration?
Silver nitrate is used in argentometric titrations because it forms insoluble silver chloride, silver bromide, or silver iodide precipitates with halide ions present in the solution. The endpoint of the titration is reached when all the halide ions have reacted with silver ions, forming a visible precipitate. This allows for precise determination of the halide ion concentration in the sample.
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.

Can we Use fajans method to determined the exact concentation of a approximate 0.01 M hcl solution?
No, Fajans method is not suitable for accurately determining the concentration of a dilute 0.01 M HCl solution. Fajans method is typically used for determining the concentration of anions in a solution, specifically for halide ions in the presence of a specially selected indicator. For accurate determination of the concentration of a 0.01 M HCl solution, titration with a suitable base such as sodium hydroxide would be more appropriate.

What are the conditions of Fajans method in Precipitation Titration?
Fajans' method makes use of two facts regarding adorption effects on precipitates of a colloidal or semicolloidal state 1. finely divided precipitates tend to adsorb o their surface ions present in the solution. by doing so, the particles become electrically charged. 2. a preciptate tend to adsorb ions common to itself. thus, a precipitate of AgCl tend to adsorb Ag/Cl- in preference to forgeign ions like NO3 and Na. Futhermore, the adsorption indicator used should not be too weakly or too strongly adsorbed by the precipitate. Otherwise, false endpoints could be observed.
When was Maksymilian Fajans born?
Maksymilian Fajans was born in 1827.
When did Maksymilian Fajans die?
Maksymilian Fajans died in 1890.
What are precipitation titrations?
Precipitation titrations involve the formation of a precipitate by adding a titrant to a solution containing the analyte. The equivalence point is reached when the precipitate just starts to form. Common examples include Mohr's method for chloride determination and Fajans method for determining halides.
