What are the properties and uses of cobalt?
Uses and properties It is magnetic. Cobalt, like iron, can be magnetised and so is used to make magnets. It is alloyed with aluminium and nickel to make particularly powerful magnets. Other alloys of cobalt are used in jet turbines and gas turbine generators, where high-temperature strength is important.
What are 3 uses of cobalt?
Uses of Cobalt Cobalt is used in alloys for aircraft engine parts and in alloys with corrosion/wear resistant uses. Cobalt is widely used in batteries and in electroplating. Cobalt salts are used to impart blue and green colors in glass and ceramics. Radioactive 60Co is used in the treatment of cancer.
What type of bond is cobalt and chlorine?
Everyone knows that a metal and a non-metal form ionic bonds and have giant structures. True, but this picture shows the structure of an isolated CoCl2 molecule in the gas phase at around 1000 K. Electron diffraction measurements show that it is a linear molecule with Co-Cl distance of 2.113 Å.
What are the uses of cobalt-60?
Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.
What are the properties of cobalt-60?
Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. Cobalt is similar to iron and nickel in its properties and can be magnetized like iron.
What is cobalt chloride paper and what it is used for?
Cobalt Chloride test paper detects the presence of moisture to determine if you have wetness or dampness problems.
What particles are in cobalt chloride?
Cobalt(II) chloride, also known as cobaltous chloride and cobalt dichloride, is a chemical compound. It contains cobalt in its +2 oxidation state. Its chemical formula is CoCl2. It contains cobalt and chloride ions.
How is cobalt 60 used in food irradiation?
Gamma irradiaton of food. Food irradiation is the process of exposing boxes or pallets of food products to radiation from a Cobalt-60 source. The ionizing radiation destroys dangerous contaminates in foods such as bacteria, viruses, fungi and insects. The process is not new; it’s been around for the past 60 years.
Why is Cobalt 60 used in food irradiation?
Cobalt-60 is the most common source of gamma rays for food irradiation in commercial scale facilities as it is water insoluble and hence has little risk of environmental contamination by leakage into the water systems.
Where is cobalt chloride used?
Hint: Cobalt chloride paper is used to test for the presence of water which may be leaking through tiny cracks carrying water. In presence of the cobalt chloride forms the hexahydrate compound which is pink in colour.
What are the characteristics of cobalt chloride paper?
The dry cobalt chloride paper is blue in colour. It changes its colour from blue to pink when it comes in contact with water. During transpiration, the water that comes out from the leaves in the form of vapours change the colour of dry cobalt chloride paper from blue to pink.
What are the properties of Cobalt 60?
The radioactive isotopes, cobalt-60, is used in medical treatment and also to irradiate food. It is used in order to preserve the food and protect the consumer. Properties Of Cobalt. It is a hard ferromagnetic, silver-white, lustrous, brittle element. It is stable in air and does not react with water. Like other metals, it can also be magnetized.
What are the medical applications of cobalt-60?
medical applications In cobalt: Occurrence, properties, and uses …the longest-lived artificial radioactive isotope cobalt-60 (5.3-year half-life) is produced by neutron irradiation in a nuclear reactor. In radioactive isotope In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer.
Is Cobalt 60 a radioactive isotope?
Cobalt-60. Cobalt-60 ( 60 Co), is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors. Deliberate industrial production depends on neutron activation of bulk samples of the monoisotopic and mononuclidic cobalt isotope 59 Co .
Why is cobalt-60 used to irradiate food?
The radioactive isotopes, cobalt-60, is used in medical treatment and also to irradiate food. It is used in order to preserve the food and protect the consumer. It is a hard ferromagnetic, silver-white, lustrous, brittle element. It is stable in air and does not react with water. Like other metals, it can also be magnetized.
