Synthetic Inorganic Chemistry

Definition:


Synthetic inorganic chemistry involves the synthesis, characterization, and study of inorganic compounds that do not naturally occur in nature.

Key Points:



  • Focuses on the preparation of inorganic compounds with specific structures and properties.
  • Employs various synthetic techniques, including sol-gel synthesis, hydrothermal synthesis, and chemical vapor deposition.
  • Aims to create materials with novel or improved properties for applications in catalysis, electronics, optics, and medicine.

Main Concepts:



  • Inorganic Compounds: Compounds that do not contain carbon atoms (except for carbon dioxide, carbon monoxide, and carbonates).
  • Coordination Chemistry: The study of metal complexes, which are compounds containing a metal ion surrounded by ligands.
  • Solid-State Chemistry: The study of the structure and bonding of inorganic solids.
  • Nanomaterials: Inorganic compounds with dimensions in the nanometer range, exhibiting unique properties.
  • Green Chemistry: Development of environmentally friendly synthetic methods.

Synthetic inorganic chemistry plays a vital role in advancing material science and technology, leading to the discovery of innovative and functional inorganic materials with diverse applications.


Preparation of Potassium Hexacyanoferrate(III)

This experiment demonstrates the synthesis of a coordination complex, potassium hexacyanoferrate(III), by a redox reaction between potassium ferrocyanide and potassium permanganate.


Materials

  • Potassium ferrocyanide (K4[Fe(CN)6]·3H2O)
  • Potassium permanganate (KMnO4)
  • Sodium hydroxide (NaOH)
  • Distilled water
  • Glassware (beaker, filter funnel, filter paper, stirring rod)

Procedure

  1. In a 250 ml beaker, dissolve 10 g of potassium ferrocyanide in 100 ml of distilled water.
  2. In a separate beaker, dissolve 5 g of potassium permanganate in 50 ml of distilled water.
  3. Add the potassium permanganate solution slowly to the potassium ferrocyanide solution, while stirring constantly.
  4. As the potassium permanganate is added, the solution will turn green and then brown.
  5. Heat the solution to 60°C and continue stirring until the solution turns a deep red color.
  6. Cool the solution to room temperature and add 10 ml of 10% sodium hydroxide solution.
  7. Filter the solution through a filter paper to remove any impurities.
  8. Evaporate the filtrate to dryness to obtain the potassium hexacyanoferrate(III) crystals.

Key Procedures

  • The reaction is a redox reaction, with potassium ferrocyanide being oxidized and potassium permanganate being reduced.
  • The reaction proceeds at 60°C in order to increase the rate of reaction.
  • Sodium hydroxide is added to the solution to neutralize the acid that is produced during the reaction.

Significance

Potassium hexacyanoferrate(III) is an important coordination complex that is used in a variety of industrial and commercial applications, including:



  • As a pigment in paints and inks
  • As a mordant in dyeing
  • As a catalyst in various chemical reactions
