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.

What is the limits for determination chloride by Volhard method?
The Volhard method is typically used to determine chloride concentrations ranging from 1-30 mg/L in water samples. This method involves titrating a silver nitrate solution with a potassium thiocyanate solution in the presence of a ferric indicator until a reddish-brown color change occurs.
How would you separate lead chloride from mixture of lead chloride and silver chloride?
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.
How do you calculate the percent chloride with the volhard method?
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.
Why is it impossible to determine iodide ion by Mohr method?
I may be off, but it has something to do with thermodynamics. The silver reacts well with chlorine and bromide, but when it comes to iodide, i would guess that the dG is too low leaving the iodide in solution. Also, if you look at the solubility of silver iodide, it is VERY high in water which doesn't give you the chance to create the precipitate needed for use in the Mohr method. Silver Chloride - white precipitate Silver Bromide - ? precipitate. Silver Chromate - red good luck.
What will happen when bromine reacts with sodium thiosulphate?
When bromine reacts with sodium thiosulfate, the bromine will oxidize the thiosulfate ion to form sulfate ions and release bromide ions. This reaction can be used as a redox titration method to determine the concentration of bromine in a solution.
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 formula of potassium chloride by crisscross method?
The formula for potassium chloride is KCl. In the crisscross method, you simply cross the numerical charges of the ions to determine the subscripts in the formula. For potassium chloride, the +1 charge of the potassium ion (K+) crosses over to become the subscript for chloride (Cl-), resulting in KCl.
What is the cris cross method of sodium chloride?
The criss-cross method is a technique used to determine the chemical formula of ionic compounds like sodium chloride. It involves swapping the numerical charges of the elements to create a balanced formula. For sodium chloride, the sodium ion (Na+) has a charge of +1, and the chloride ion (Cl-) has a charge of -1, so the formula becomes NaCl.
What is the limits for determination chloride by Volhard method?
The Volhard method is typically used to determine chloride concentrations ranging from 1-30 mg/L in water samples. This method involves titrating a silver nitrate solution with a potassium thiocyanate solution in the presence of a ferric indicator until a reddish-brown color change occurs.
What do you call the method to make silver chloride?
The method to make silver chloride is called precipitation reaction. It involves adding a soluble chloride compound, such as sodium chloride, to a solution containing silver ions, resulting in the formation of insoluble silver chloride as a white precipitate.
What is the classical method of Cubr2?
The classical method for preparing CuBr2 involves reacting copper oxide or carbonate with hydrobromic acid. This reaction forms copper bromide and water as products. The balanced chemical equation for this reaction is CuO + 2HBr -> CuBr2 + H2O.
Speration method for sodium chloride solution and sodium chloride?
if u have sodium chloride solution just heat it..water will get evaporated leaving only sodium chloride
What is the recommended method for safely neutralizing ferric chloride using a ferric chloride neutralizer?
The recommended method for safely neutralizing ferric chloride is by using a ferric chloride neutralizer. This substance helps to safely and effectively neutralize the acidic properties of ferric chloride, making it less harmful to the environment and easier to dispose of.
How can you determine the chloride in soap?
If the soap is fully and completely water soluble, its chloride content can be precipitated by adding silver nitrate solution to the soap solution, and the amount of silver chloride solution used until precipitation ceases measures the content of sodium originally in the solution. There are also many other analytical methods available.
What is the principle of aluminium chloride method?
The principle of the aluminium chloride method involves using aluminium chloride as a catalyst to promote the Friedel-Crafts acylation or alkylation reaction. This method is commonly used in organic chemistry to introduce new functional groups onto aromatic compounds. The aluminium chloride coordinates with the electrophile and enhances its reactivity towards the aromatic ring.
How do you determine integral heat of solution of ammonium chloride by the calorimeteric method?
To determine the integral heat of solution of ammonium chloride by the calorimetric method, you would dissolve a known mass of ammonium chloride in a known volume of water in a calorimeter. Measure the temperature change that occurs during the dissolution process to calculate the heat absorbed or released. Use the formula q = mcΔT, where q is the heat, m is the mass of the solution, c is the specific heat capacity of the solution, and ΔT is the temperature change.
What is the separation technique for Silver chloride and sodium trioxonitrate?
Silver chloride is insoluble in water; filtration is a simple method.
