Cerium(IV) sulfate, also called ceric sulfate, is an inorganic compound. It exists as the anhydrous salt Ce(SO 4) 2 as well as a few hydrated forms: Ce(SO 4) 2 (H 2 O) x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids.
You will conduct an oxidation-reduction reaction in this experiment in order to determine the amount of iron (II) ions in a solid sample of ferrous ammonium sulfate hexahydrate, (NH4)2Fe(SO4)2•6H2O. The oxidizing agent for the sample will be ammonium cerium (IV) nitrate, (NH4)2Ce(NO3)6. The net ionic equation for the reaction is shown below.

CERIC SULPHATE TITRATION METHODS . Ammonium ceric sulphate serves as a powerful oxidizing agent in an acidic medium. The salt has a bright yellow colour and so its solution. On reduction, the resulting cerous salt obtained is colourless in appearance and, therefore, strong solutions may be considered as self-indicating.

For 0.02 M titrant and assuming 50 mL burette, aliquot taken for titration should contain about 0.2-0.25 g of iron (3.5-4.5 millimoles). end point detection As usual in the case of permanganate titrations, pink color of excess permanganate is strong enough so that there is no need for any other end point indicators.
three drops of ferroin indicator solution and titrate drop-wise with ceric sulfate solution (0.1N) until the indicator changes to a blue color. 3. Add the weighing bottle containing the sample to the cold solution and swirl to mix. Titrate rapidly with ceric sulfate solution (0.1N) to the same blue color. 4. Let the titration obtained be A mL.
Ammonium ferrous sulfate or ammonium iron(II) sulfate is called Mohr's salt. It is an inorganic light green coloured crystalline salt. Mohr's salt formula is Fe(SO 4)(NH 4) 2 SO 4 (anhydrous). Formula of hydrated Mohr's salt is Fe(SO 4)(NH 4) 2 SO 4.6H 2 O. It is hexahydrate salt. Thus, it has two different cations Fe 2+ and NH 4 + . So ...

Nov 27, 2012· Then, 25 mL of ammonium sulfate and cerium was added to 2 g of potassium iodide and 150 mL of water. This was titrated immediately with 0.1 M sodium thiosulfate, using 1 mL of starch solution as an indicator. Solution of ammonium sulfate and 0.01 M cerium: 50 mL of ammonium sulfate and 0.1 M cerium was diluted with 500 mL water.

It is a red-ox titration. Ceric ammonium sulphate solution is titrated with arsenic xide (primary standard) in presence of sulfuric and osmic acid utilizing the ferroin sulphate as indicator. End point is visually detected by change in color from pink to very pale blue.1
1 CHEM 2211 Experiment Eight Potentiometric Titration of Iron(II) OBJECTIVE: The objectives of this experiment are: Conduct a potentiometric titration of the reaction between ferrous ammonium sulfate and ammonium cerium (IV) nitrate. Measure the potential change of the reaction. Determine the molar concentration of iron(II) ions in a sample of unknown concentration.
ammonium iron(II) sulfate solution. The iron(II) solution is measured by use of a pipette, whilst the potassium manganate(VII) solution is placed in a burette. The titration is carried out under acidic conditions, so the pipetted Fe +2 solution is acidified by addition of about 10 cm 3 of dilute sulfuric acid before commencement of the titration.

Incubation of Staphylococcus aureus with increasing concentrations of ferrous ammonium sulfate (0-1,000 uM) progressively increased the iron content in the bacteria (from 0.01-0.24 umol of iron per 109 bacteria). Iron loading of the bacteria markedly increased their susceptibility to killing by H2O2. After 1 hr of incubation with 1 mM H2O2, 95 +/- 2% of the iron-loaded bacteria were killed ...
A method has been developed for the titration of cerium(IV) sulphate with sodium oxalate at the room temperature, using ferroin as internal indicator. A new principle has been utilised for facilitating the indicator action at the equivalence point. This involves the use of a photochemical reaction between the oxalate and iron(III) which is deliberately added to the mixture containing cerium(IV ...
The Ceric sulfate dosimeter can be used to measure doses in the range 0.01 to 100 M rad. It is the only chemical dosimeter that may be regarded as a reference standard for aerated ferrous sulfate solution. However, the most serious disadvantage of Ceric sulfate .
Transition Metal Activation. Ferrous iron (Fe 2+) is the most commonly used and readily available activator for transition metal catalysis.It's generally applied in the form of ferrous sulfate (FeSO4) and ferrous chloride (FeCl2). To effectively activate persulfate 100 to 250 mg/L of iron is generally required.
