To calculate the percent chloride using the Volhard method, you measure the excess silver nitrate used to titrate the chloride ions in the sample. You then use the volume of excess silver nitrate and the molarity of the silver nitrate solution to calculate the moles of chloride present. Finally, calculate the percent chloride by dividing the moles of chloride by the sample weight and multiplying by 100.
Nitrobenzene is used in the Volhard method to ensure the complete precipitation of silver chloride by complexing with any excess silver ions before the addition of titrant. This prevents the end point from being reached prematurely and allows for the accurate determination of the halide ion concentration in the sample.
The Mohr method for determining chloride ions has a detection limit of around 10-20 ppm and a quantitative limit of around 30-40 ppm. These limits can vary depending on the specific conditions and equipment used in the analysis.
One method to separate lead chloride from a mixture of lead chloride and silver chloride is to dissolve the mixture in water, then add hydrochloric acid to precipitate the lead chloride while keeping the silver chloride in solution. The precipitated lead chloride can then be filtered out. Another method is to use selective precipitation by adding a potassium chromate solution, which will form a yellow precipitate with the lead chloride while leaving the silver chloride in solution.
I want to assmue the the readers of this answer have know the details theory and calculations about Mohr method if not u can refer to Any analytical text for reference. Well, Bromide and Chloride can not be determine simultaneously in a sample using Mohr method , the reason be that the indicator use for each of them is different. and there will be problem in the procedure if ones try to determine both simultaneously. To determine Chloride Ion, Ammonium or Potassium Thiocynate is used as indicator and the sample must be neutral or slightly acidic. while Eosin indicator is use for the determination of Bromide Ion and the same neutral solution is prefer for this purpose, the solution must be adjusted to neutral either by adding small amount of Nitric acid or by adding small amount of carbonate as the case maybe. But, in the determination of each of them Silver Nitrate is use for the titration of both and this is the similarity they shared and the experimental procedure is quite the same. Olajire Mojeed
The Mohr method is typically preferred over the Volhard method for chloride titrations because it does not require a silver nitrate standard solution, making it more cost-effective and simpler to execute. Additionally, the Mohr method is more precise as it allows for a direct endpoint determination based on the formation of a specific silver chloride precipitate.
An acidic titration medium is required in a Volhard method for chloride determination because it prevents the precipitation of silver chloride as a solid. Keeping the solution acidic ensures that the silver chloride formed during the titration remains in solution as AgCl^- ions, allowing for accurate measurement of the endpoint.

Nitric acid is used in the Volhard method to oxidize Fe(II) to Fe(III) in order to prevent interference in the titration of chloride ions with silver nitrate. By converting Fe(II) to Fe(III), nitric acid ensures accurate and precise results in the determination of chloride content.
Back titration is used in the Volhard method when the analyte interferes with the primary titration method. This allows for the determination of the interfering substance before the main titration is carried out. It provides more accurate results by isolating the interfering substance and ensuring that it does not affect the primary titration.
The Volhard method is a titration method used to determine the concentration of halide ions in a solution using silver nitrate and potassium chromate as indicators. The Mohr method, on the other hand, is also a titration method used to determine the chloride ions concentration in a solution using silver nitrate and potassium chromate indicators. The key difference lies in the end point detection: Volhard method involves the use of a ferric alum indicator that forms a red-brown precipitate, while the Mohr method involves the formation of a red-brown silver chromate precipitate.

The Mohr method is used in neutralization solutions to determine the concentration of chloride ions or substances that can be precipitated as silver chloride. By titrating the solution with a standardized silver nitrate solution using a chromate indicator, the endpoint is reached when all chloride ions have reacted to form a white precipitate. This method allows for accurate determination of chloride concentration in solution.
The Volhard method is a chemical titration method used to determine the concentration of halide ions, such as chloride, bromide, or iodide, in a sample. It involves adding a silver nitrate solution to the sample to form a precipitate, which is then back-titrated with a standard solution of thiocyanate ion to determine the halide concentration.
