Precipitation and Co-precipitation01:17

Precipitation and Co-precipitation

3.6K
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...

Spontaneous Chemical Reactions
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...

Electrodeposition01:08

Electrodeposition

1.1K
Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.
Electrodeposition can...

Extraction: Advanced Methods

921
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Conductors and Insulators01:19

Conductors and Insulators

10.1K
Some materials may easily let electrical charges pass through them, while others obstruct their flow. The former are called conductors and the latter insulators. The atomic structures of materials determine whether they are conductors or insulators of electricity.
Most metals are conductors. Their atomic configuration is such that one or more electron(s) are loosely bound to the nucleus in each atom. Thus, a sea of mobile electrons are available in them, known as free electrons. Their easy...

Theory of Metallic Conduction01:17

Theory of Metallic Conduction

1.6K
The conduction of free electrons inside a conductor is best described by quantum mechanics. However, a classical model makes predictions close to the results of quantum mechanics. It is called the theory of metallic conduction.
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...

Area of Science:

  • Biochemistry
  • Nutritional Science
  • Genetics

Background:

  • Copper is an essential micronutrient vital for numerous enzymatic functions and maintaining homeostasis.
  • Copper deficiency is uncommon but can arise in conditions affecting nutrient absorption, such as post-bariatric surgery.

Observation:

  • A 70-year-old male, following a duodenal switch procedure, presented with copper deficiency.
  • The deficiency persisted despite intensive oral and intravenous copper supplementation.

Findings:

  • The patient's refractory copper deficiency led to further investigation.
  • Underlying heterozygous Wilson's disease was diagnosed as the cause of the persistent deficiency.

Implications:

  • This case underscores the importance of considering genetic disorders in refractory nutrient deficiencies.
  • It suggests that Wilson's disease should be evaluated in patients with unexplained copper deficiency, especially post-bariatric surgery.
