Why HCl is used in titration of mohr salt and potassium dichromate?
so that ferrous doesnot get converted into ferric
What is mohr's salt test?
Chlorides will be dosed by titration with Silver nitrate (AgNO3) in the presence of potassium chromate (K2CrO4) as indicator. Salinity was expressed in mg NaCl/L of treated oil.
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 Mohr salt is called Mohr?
Mohr salt is (NH4)2Fe(SO4)2·6H2O. This name was attributed in the honor of the German chemist Karl Fiedrich Mohr.
What is mohr salt?
Mohr Salt is Ammonium Iron (II) Sulphate, named after the German chemist Karl Friedrich Mohr.
What is the equivalent weight of mohr's salt in the titration of pottasium permanganate and mohr's salt?
E Mohr salt 392/1

Why we add conc sulphuric acid in mohr salt in the titration of mohr salt against potassium dichromate?
For preparation of standard solution of Mohr salt {FeSO4.(NH4)2SO4.6H2O}, it's necessary to add dilute H2SO4 to prevent the Fe2+ ions of Mohr salt solution from undergoing oxidation (to Fe3+).
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 are the limits for determination of chloride by the Mohr method?
1- done only in neutral medium. 2- all the cations which give insolublld be chromate must be absent or removed before titration. 3-titration of Ag+ with Cl- is not feasible. 4- not suitable for I- and SCN-

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
