Cobalt chloride attacks the blood, liver, thyroid, lungs and connective tissues. It is an eye and respiratory tract irritant and a skin sensitiser. Eye contact causes redness and pain. Skin contact may produce an allergic response in previously sensitised individuals. Is cobalt chloride harmful to the body? Effects of long-term Read more…
Chemical compounds Cobalt comes in two oxidation states, +2 and +3. Most soluble cobalt compounds are red. They can also be green, blue, brown, and black. What color is cobalt usually? silvery-blueA lustrous, silvery-blue metal. It is magnetic. Cobalt, like iron, can be magnetised and so is used to make Read more…
Tonal colors, such as cobalt blue and a pastel blue complement each other extremely well. The lighter shade softens the look, while the cobalt adds a nice pop. What color looks best with cobalt blue? Cobalt blue works well with all colours — try it with black, navy, white, camel, Read more…
Chemical compounds. Cobalt comes in two oxidation states, +2 and +3. Most soluble cobalt compounds are red. They can also be green, blue, brown, and black. Why is cobalt red? Subsequent determinations of the crystal structures of a variety of compounds have confirmed this view. The red colour of an Read more…
A semi-transparent, bright, bluish-green with a low tinting strength, cobalt green is extremely permanent – like many pigments produced at high temperatures. In 1780, the process for making a compound of cobalt and zinc was developed by the Swedish chemist Sven Rinman. What is cobalt green used for? Cobalt green Read more…
With the addition of varying amounts of other metals or minerals, cobalt can be more magenta or more purple. What color is cobalt purple? Cobalt Violet – Cobalt Violet is a deep violet that is cool in its masstone and less red than Manganese Violet. Although muted and greyed down Read more…
Cobalt is mainly produced as a by-product at assets that produce copper or nickel. What is cobalt a byproduct of? Most cobalt is produced as a byproduct of the processing of copper and nickel ores. What are the byproducts of copper? By-products generated in the process are sulfur dioxide and Read more…
Cobalt-57. Used in nuclear medicine to help physicians interpret diagnostic scans of patients’ organs, and to diagnose pernicious anemia. What are uses for cobalt-57? Radioisotope Cobalt-57 is used to manufacture standards and sources for calibration of radiometric equipment and medical gamma-cameras. It is also applied in various studies as a Read more…
59Co. Naturally occurring cobalt (27Co) consists of a single stable isotope, 59Co. Twenty-eight radioisotopes have been characterized; the most stable are 60Co with a half-life of 5.2714 years, 57Co (271.8 days), 56Co (77.27 days), and 58Co (70.86 days). What are the two isotopes of cobalt? Naturally occurring cobalt is composed Read more…
Cobalt-60 and cobalt-59 are isotopes. This means that while they have the same number of protons (proton number determines the identity of the isotope), they have different mass numbers because they contain different numbers of neutrons. How are cobalt-60 and cobalt-59 the same element? Cobalt-59 and cobalt-60 are called isotopes Read more…
