Thallium, then, like its congeners, is a soft, highly electrically conducting metal with a low melting point, of 304 °C. [ 11 ] A number of standard electrode potentials, depending on the reaction under study, [ 12 ] are reported for thallium, reflecting the greatly decreased stability of the +3 oxidation state: [ 11 ]
Normal background blood and urine concentrations in healthy persons are usually less than 1 μg/litre, but they are often in the 1–10 mg/litre range (1,000–10,000 times higher) in survivors of acute intoxication. [10] [11] Thallium is present in the blood for a very short time so urine testing is usually most appropriate. A quick way to ...
The characteristic bluish-green color of the flame is due to the copper. A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis .
Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive caesium poisoning. [1] [2] For thallium it may be used in addition to gastric lavage, activated charcoal, forced diuresis, and hemodialysis. [3] [4] It is given by mouth or nasogastric tube.
Prussian blue pigment is significant since it was the first stable and relatively lightfast blue pigment to be widely used since the loss of knowledge regarding the synthesis of Egyptian blue. European painters had previously used a number of pigments such as indigo dye , smalt , and Tyrian purple , and the extremely expensive ultramarine made ...
Example thallide monoclinic Cs 7.29 K 5.71 Tl 13 containing [Tl 6] 6− and [Tl 7] 7− clusters. Thallides are compounds containing anions composed of thallium.There are several thallium atoms in a cluster, and it does not occur as a single Tl − in thallides.
Thallium(I) sulfate is soluble in water and its toxic effects are derived from the thallium(I) cation. The mean lethal dose of thallium(I) sulfate for an adult is about 1 gram. Since thallium(I) sulfate is a simple powder with indistinctive properties, it can easily be mistaken for more innocuous chemicals.
