No not really, if you swallow it, it can harm you internally, but when I dipped my finger into it (accidentally thinking it was water), nothing happened. If this happens to you, you should carefully rinse your fingers, so it doesn't go into your body, and damage you.
Well, if you drop a large bag of it on your head, yes. It's not particularly poisonous and is in fact used as a food additive, though in fairly small quantities (it has a rather unpleasant taste in high concentrations, much like the related magnesium aluminum sulfate, or alum).
Pure, raw sodium? Yes, it'll burn through your skin. Sodium as in Sodium Chloride is safe (NaCl/salt.)

· In analytical chemistry, sodium thiosulphate is used for the determination of the strength of a given solution of iodine. · Sodium thiosulphate is preferred in iodometric analysis due to the fact that sodium thiosulphate is oxidized by iodine. It is also used to determine the strength of many oxidizing agents.

naaa then
The polyatomic anions in sodium sulphate have the formula SO4-2, while the polyatomic anions in sodium thiosulphate have the formula S2O3-2.
Sodium thiosulphate is a somewhat strong acid with pKas of 0.6 and 1.7 for the first and second dissociation respectively.

In iodometry sodium thiosulphate is used because it is standardized by potassium dichromate and it is the best and relaible way to standardized sodium thiosulphate using iodometric titration. Infact sodium thiosulphate is also standardized by iodimetry. The difference between both of them is only of iodine. In iodometry iodine gas is liberated that will further react with sodium thiosulphate but in iodimetry standard solution of iodine is used.

It is a colourless crystal.
The boiling point of sodium thiosulphate is 100 degrees Celsius, the same as water.That would be 212 degrees Fahrenheit.
because sodium thiosulphate is unstable and iodine also so to maintain neutral medium we have to use sodiumcarboate
Because it used to be called Sodium hyposulphite.
Because it is :)
