Weight of Mohr's salt required to prepare 1000 ml of 1 M solution = 392 g. Therefore, weight of Mohr's salt required to prepare 250 ml 0.05 M Mohr's salt solution = Determination of strength of KMnO 4 using standard solution of Mohr's salt. In this titration, potassium permanganate is the oxidizing agent and Mohr’s salt is the reducing agent.

D: Salt content of Wholemeal Bread by Mohr Titration versus by AAS Moreover, the amount of the sample size used in the Mohr titration using white brea d as 24 samples and 1.995 gram ± 2.091 gram bread contained grams of salt in range 26,00mg ± 39,84 mg. Mohr’s salt is an inorganic compound which is a double salt with the formula (NH 4) 2 Fe(SO 4) 2 (H 2 O) 6. It is a common laboratory reagent with IUPAC name ammonium iron(II) sulfate. Mohr’s salt is named after German Chemist Karl Fredrich Mohr.

For Example $$\ce{Na3PO4 + BaCl2 -> NaCl + Ba3(PO4)3}$$ N factor of $$\ce { Na3PO4} $$ is 3. samples taken during the olive fermentation period were analyzed for the salt content by Mohr titration method. The method was validated using 3 fortified samples (Fortified of water with salt solutions, cracked olive’s brine and olive) matrices spiked at 3, 5 and 7% salt concentration at three different times.

So n factor is 1 . Structure of ferrous ammonium sulfate with hydrogen bonding network highlighted (N is violet, O is red; S is orange, Fe = large red).
