An indicator blank is used in the Mohr method to account for any color changes that may occur due to impurities in the indicator itself. By measuring the blank, you can subtract this error from the titration result, ensuring accurate determination of the analyte concentration.

Why is mohr method suitable for use in neutral solutions only?
Well, honey, the Mohr method is suitable for use in neutral solutions only because it relies on a chromate indicator that changes color at a specific pH range. If the solution is too acidic or basic, the indicator won't work its magic properly. So, if you want accurate results, stick to neutral solutions with this method.
What is the difference between volhard and mohr methods?
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.
Why mohr method used with cl and br?
The Mohr method is used for the determination of chloride (Cl) and bromide (Br) ions in a solution due to its simplicity and effectiveness in visual titration. It involves the addition of a silver nitrate solution to the sample, which forms a colored precipitate with these halides. The endpoint is indicated by a color change, typically using a chromate indicator that forms a reddish-brown precipitate of silver chromate once all halides are precipitated. This method is advantageous for its accuracy and rapidity in detecting halide concentrations in various samples.
What is the indicator used in EDTA method?
The indicator used in the EDTA method is typically Eriochrome Black T, or its chelates. This indicator changes color in the presence of metal ions, helping to determine the endpoint of the complexometric titration involving EDTA and metal ions.
Name the indicator used in the edta method?
Erio Chrome Black-T, is usually used as indicator. It is commonly known as EBT. EBT can easily form weak complex ,which can be replaced easily by Sequencing agent Ethylene Diammine Tetra Acetic acid
Why we used mohr method in neutralization solution?
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.

What is the use of ferroin indicator in redox titration of Mohr's salt?
Ferroin indicator is used in the redox titration of Mohr's salt as it changes color when the Fe2+ ions are completely oxidized to Fe3+ ions. This color change helps in determining the end point of the titration, where all the Mohr's salt has been oxidized and no more Fe2+ ions are present.
What is a mohr method?
Mohr method is a Precipitation titrations method which is the concentration of an unknown substance in solution is determined by adding measured amount of a standard solution such as AgNO3 that react with unknown samples to determine CL, Br in Solid and solutions samples . NaCL + AgNO3 =====> AgCL + NaNO3. Br- + Ag NO3=====> AgBr + NO3- Then the concentration of the unkown can be calculated using the stoichiometry of the recation and the number of moles of standard solution needed to reach the End point. The mohr method uses chromate CrO4 2- ion as an indicator . By Known the stoichiometry and moles consumed at end point,we can determine the mount of chloride in an unknown samples.

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.
Double indicator method?
A double indicator method is used in many different aspects of the medical field. This can be used during surgeries, physical therapy, and patient counseling.

Can chloride and bromide simultaneously determine by Mohr method?
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

What is an indicator blank?
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
