Sodium extract is commonly used for detecting elements because it has a high sensitivity to the presence of certain metal ions. When a sample is exposed to the sodium extract, emission lines are produced that can be analyzed to determine the elemental composition of the sample. This method is particularly useful in spectroscopic analysis.
firstly, take 1ml of sodium silicate and add 99ml of water. titrate it with 0.5N HCl and use 1 drop phenophthalein as indicator. the amount of HCl used is converted to gram by using the density and molecular weight calculations. 1.177gm of HCl used for 1 gm of sodium oxide, calculate by multiplying your HCl used for your sodium oxide. now take 10ml of silicate and weigh it in grams and heat it at 180 degrees celsius for 2 hours to get solid content (water evaporated) deduct the value of sodium oxide from total solid content obtained. this is the value of silica in your sodium silicate.
The chemical formula for sodium selenate is Na2SeO4.
No, selenium and selenate are not the same. Selenium is a chemical element with atomic number 34, while selenate is the anionic form of selenium usually found in compounds like sodium selenate. Selenate is a common form of selenium used in supplements and as a source of selenium in the environment.
Selenate can be converted to selenium through a reduction process. This reduction can be achieved through biological means, using bacteria or other microorganisms that are capable of reducing selenate to elemental selenium. Alternatively, a chemical reducing agent such as sodium sulfite or sodium borohydride can be used to convert selenate to selenium.
Hi, According to the MSDChem website it is classified as an ion/group/compound and is a non-polymer. this website will give some more detail http://www.ebi.ac.uk/msd-srv/msdchem/cgi-bin/cgi.pl?FUNCTION=getByCode&CODE=SE4 hope this helps

There are several analytical methods to identify sodium both qualitatively and quantitatively. To name just a few, since sodium is a metal, any analysis for metals including ICP (inductively coupled plasma) or XRF (X-ray diffraction) will identify sodium. Also, since sodium can exist as a charged ion, ion chromatography is another possibility.
