Mohr's method indicator
WebHere we have discussed an example of precipitation titration. Example – To determine the concentration of chloride ion in a certain solution we can titrate this solution with silver nitrate solution (whose concentration is known). The chemical reaction occurs as follows: Ag + (aq) + Cl – (aq)→ AgCl (s). AgCl in the form of a white ... WebMohr’s method is a type of precipitation titration used to determine the concentration of chloride ions in a solution. It is based on the reaction between silver nitrate (AgNO3) and chloride ions (Cl-) in an aqueous solution to form a silver chloride (AgCl) precipitate. The Mohr’s method involves the addition of a known volume of silver ...

WebMohr’s titration method is used to determine both the chloride ions and the bromide ions (if present). However, if one is using seawater, the concentration of the bromide ions will be … WebThe method is applicable to the direct determination of dissolved chloride in concentrations between 5 mg/l and 150 mg/l. The working range may be extended to 400 mg/l by using a burette of larger capacity or by sample dilution. Due to many interferences the method is not applicable to heavily polluted waters of low chloride content.
WebThe excess silver is then back titrated using a standardized solution of potassium or ammonium thiocyanate with ferric ion as an indicator. The amount of silver that is precipitated with chloride in the sample solution is calculated by subtracting the excess silver from the original silver content.

WebMohr method. The Mohr method was first published in 1855 as a method for chloride analysis. • In the precipitation of chloride by silver ion, chromate ion (CrO. 4 2. −) is used as an indicator in the formation of Ag. 2. CrO. 4, a reddish-brown precipitate formed when excess Ag + is present. Ag + +Cl. −. AgCl (s) titrant analyte white ... WebThe first type of indicator is a species that forms a precipitate with the titrant. In the Mohr method for Cl – using Ag + as a titrant, for example, a small amount of K 2 CrO 4 is …

WebMOHR'S method is said to be inapplicable to the titration of chlorides of metals which hydrolyse at the pH range within which the titration must be operated ; hence it would be expected that the mere presence of such ions would have a baneful effect on the titration.
