What is Ceric Ammonium sulphate?
Ammonium cerium(IV) sulfate is an inorganic compound with the formula (NH4)4Ce(SO4)4ยท2H2O. It is an orange-colored solid. It is a strong oxidant, the potential for reduction is about +1.44V. Cerium(IV) sulfate is a related compound.
Is Ceric sulphate a self indicator?
These advantages include increased stability, ability to be used in a high concentration of Hydrochloric Acid (where Potassium Permanganate is unsuitable), lack of intense coloration (which would impair the ability to read a buret or other volumetric glassware), and a colorless reduced form (Cerous ion, Ce3+) that can …
Why is Ceric sulfate prepared with sulfuric acid?
Ceric sulphate solutions must be kept acidic to prevent hydrolysis or polymerization. Solutions were maintained 0.80 N in sulphuric acid unless otherwise stated, this concentration being chosen because most of the radiation- induced oxidation of ferrous ion has been carried out with this acid at this concentration.
What is the formula of Ceric sulphate?
Ce(SO4)2
Cerium(IV) sulfate/Formula
What is Ceric sulfate used for?
Ceric sulfate is used in analytical chemistry for redox titration, often together with a redox indicator. A related compound is ceric ammonium sulfate. The solubility of Ce(IV) in methanesulfonic acid is approximately 10 times the value obtainable in acidic sulfate solutions.
Is Ceric Ammonium sulphate is oxidizing agent?
Ceric ammonium sulphate and potassium permanganate are used as oxidizing agents in acidic medium for oxidation of ferrous ammonium sulphate to ferric sulphate.
Which indicator is used in Ceric Ammonium sulphate?
ferroin sulphate
Ceric ammonium sulphate solution is titrated with arsenic trioxide (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.
How do you make Ceric sulfate solution?
Ceric Ammonium Sulphate Solution Preparation Dissolve 65 g of ceric ammonium sulfate with the aid of gentle heat, in a mixture of 30 ml of sulphuric acid and 500 ml of water. Cool, filter the solution, if turbid, and dilute to 1000 ml with water.

How is Ceric Ammonium sulphate standardized?
Ceric Ammonium Sulphate Solution Standardization Add 30 ml of dilute sulphuric acid, 0.15 ml of osmic acid solution, 0.1 ml of ferroin sulfate solution. Titrate with the ceric ammonium sulfate solution until the pink color is changed to a very pale blue, adding the titrant slowly towards the end-point.
What is Ceric Ammonium Nitrate test?
The ceric ammonium nitrate test is a way to examine a solution for the presence of either alcohols or phenols. In solution, the orange-yellow ceric ammonium nitrate makes a complex with the alcohol or phenol, which results in a color change.
How is Ceric ammonium sulphate standardized?
What is ceric sulfate?
Ceric Sulfate is a powerful and versatile oxidizing agent that possesses certain advantages over Potassium Dichromate and Potassium Permanganate.
What is the solubility of ceric salts?
However, Ceric salts, such as Ceric Ammonium Sulfate and Ceric Ammonium Nitrate, are relatively expensive and do not dissolve readily in water or dilute acid solutions due to hydrolysis and precipitation of Ceric Hydroxide. Solutions of these salts are difficult to prepare and must be made in stronger (1 – 2 Normal) acid levels.
Is ammonium ceric sulphate self indicating?
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.
What are the alternatives to ceric ammonium sulfate titrants?
Ceric Sulfate solutions may be used in place of Ceric Ammonium Sulfate and Ceric Ammonium Nitrate titrants. Ceric Sulfate solutions can be standardized with Arsenic Trioxide using Osmium Tetroxide as catalyst and Ferroin as indicator.
