Why silver nitrate reacts with chloride ions before chromate ions in Mohr's method?
In Mohr's method, silver nitrate reacts with chloride ions before chromate ions due to the differing solubilities of their respective silver salts. Silver chloride (AgCl) is highly insoluble in water, leading to its immediate precipitation upon contact with chloride ions. In contrast, silver chromate (Ag2CrO4) is less soluble, meaning that the reaction with chromate ions occurs only after all available chloride ions have been precipitated as AgCl. This selective reaction allows for accurate titration and detection of chloride ions.
What is n factor of mohr's salt in solid state?
The n factor of Mohr's salt in solid state is 2. This is because each formula unit of Mohr's salt contains two moles of electrons that can be lost in a redox reaction.
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+).
What is the equivalent weight of mohr's salt in the titration of pottasium permanganate and mohr's salt?
The equivalent weight of Mohr's salt (ammonium iron(II) sulfate) is the molecular weight divided by the total positive charge of the cation(s) that are being titrated. In the titration of potassium permanganate with Mohr's salt, the equivalent weight of Mohr's salt is 88 g/mol (molecular weight) divided by the total positive charge of the cation(s) (in this case, 2), which equals 44 g/equivalent.
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.
