What is Argentometry in chemistry?
In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration.
What is volhard’s method?
Definition of Volhard method : a method for the determination of chlorine, bromine, and iodine in the form of halides by precipitating them with excess silver nitrate and titrating the excess with a thiocyanate solution.
What is mohrs method?
This method determines the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added, a precipitate of silver chloride forms. Ag+(aq) + Cl–(aq) → AgCl(s) The end point of the titration occurs when all the chloride ions are precipitated.
What do you mean by Argentometric titration?
Definition: The process of determining the quantity of a sample by adding measured increments of a titrant until the end-point, at which essentially all of the sample has reacted, is reached.
What is the another name of argentometric titration?
This is a general presentation about Argentometric Titration or well known as Precipitation Titration. Contain Mohr Methods, Volhard Methods, and Fajans Methods.
What is back titration?
Back titration is a titration done in reverse; instead of titrating the original sample, a known excess of standard reagent is added to the solution, and the excess is titrated.
What is the role of Kscn in the titration?
The KSCN is added to displace the adsorbed I2 making it accessible to the starch collodial particles, hence yielding a sharper endpoint. The iodine will be titrated with a standardized solution of sodium thiosulfate (Na2S2O3). This is what your sample should look like at the end-point of the titration.
