Preparation and standardization molar and normal solutions of Ceric ammonium sulphate

Preparation and standardization molar and normal solutions of Ceric ammonium sulphate

Ceric ammonium sulfate, also known as ammonium cerium (IV) sulfate, is a chemical compound that is commonly used as an oxidizing agent in analytical chemistry. Here are the steps for preparing and standardizing molar and normal solutions of ceric ammonium sulfate:

Preparation of ceric ammonium sulfate solution:

  1. Weigh out the appropriate amount of ceric ammonium sulfate (CAS) into a clean and dry beaker or flask. The amount of CAS required will depend on the desired concentration of the solution.
  2. Add distilled water to the beaker or flask and stir until the CAS is completely dissolved.
  3. Transfer the solution to a volumetric flask and make up to the desired volume with distilled water.
  4. Mix the solution thoroughly.

Standardization of ceric ammonium sulfate solution:

  1. Weigh out a known amount of a standard reducing agent, such as ferrous ammonium sulfate (FAS) or oxalic acid.
  2. Dissolve the standard reducing agent in distilled water in a clean and dry beaker or flask.
  3. Add a few drops of indicator solution, such as diphenylamine sulfonate, to the beaker or flask.
  4. Titrate the standard reducing agent solution with the ceric ammonium sulfate solution until the endpoint is reached, as indicated by a color change in the indicator solution.
  5. Record the volume of ceric ammonium sulfate solution used in the titration.
  6. Repeat the titration at least two more times to ensure accuracy and consistency.
  7. Calculate the concentration of the ceric ammonium sulfate solution using the volume and concentration of the standard reducing agent solution.

Standardization of molar and normal solutions: To standardize a molar or normal solution of ceric ammonium sulfate, follow the same steps as for standardizing a regular solution, but calculate the concentration of the solution in terms of moles or equivalents of ceric ammonium sulfate per liter of solution, respectively.

Note: It is important to handle ceric ammonium sulfate with care, as it is a strong oxidizing agent and can be hazardous if not used properly. Always wear appropriate personal protective equipment and follow all safety protocols when working with this chemical.
